SUMMARY:Twistorial constructions of higher genus integrability
DESCRIPTION:Quantum Field Theory and Physical Mathematics Seminar \nSpeaker: Seraphim Jarov\, Perimeter Institute \nTitle: Twistorial constructions of higher genus integrability \nAbstract: I will present a new method to engineer integrable models in 4d with higher genus spectral parameters. The method has a twistorial origin – by working on a branched covering of twistor space\, I show how one can derive deformations of holomorphic BF theory on twistor space which descend to elliptic and hyperelliptic models on R^4 via the Penrose transform. I show how one can bootstrap the Penrose transformed actions using symmetry and integrability to find deformations of self-dual Yang-Mills theory. I will also discuss some novel deformations of a BF type description of Hitchin’s equations. This is based on my paper: 2509.12486

SUMMARY:A Mumford form on infinite Grassmannians
DESCRIPTION:Joint Math/CMSA Geometry and Quantum Theory Seminar \nSpeaker: Oswaldo Vázquez (Harvard) \nTitle: A Mumford form on infinite Grassmannians \nAbstract: The Polyakov measure in bosonic string theory can be expressed in terms of the Mumford form\, which is a trivializing section of a product of determinant line bundles over the moduli space of genus g curves. We will discuss the work in https://arxiv.org/abs/2412.18570\, which reviews how the moduli space can be embedded in an infinite dimensional Grassmannian as a Virasoro orbit and generalizes the Mumford form to other such orbits. In particular\, this “universal Mumford form” can be described in terms of coordinates in the Grassmannian\, which are amenable to computation and thus could have implications to the evaluation of amplitudes. \n

SUMMARY:Multiplicities of graded families of ideals on Noetherian local rings
DESCRIPTION:Algebra Seminar \nSpeaker: Dale Cutkosky\, University of Missouri \nTitle: Multiplicities of graded families of ideals on Noetherian local rings \nAbstract: Let $R$ be an arbitrary $d$-dimensional Noetherian local ring with maximal ideal $m_R$. In this talk\, we give a generalization of the multiplicity $e(I)$ of an $m_R$-primary ideal $I$ of $R$ to a multiplicity $e(\mathcal I)$ of a graded family of $m_R$-primary ideals $\mathcal I$ in $R$. This multiplicity gives the classical multiplicity $e(I)$ if $\mathcal I=\{I^n\}$ is the $I$-adic filtration\, and agrees with the volume\, $\lim_{n\rightarrow \infty}d!\frac{\ell(R/I_n) }{n^d}$ for $R$ such that $\dim N(\hat R)>d$\, the required condition for the volume of graded families of $m_R$-primary ideals to exist as a limit. We will show that many of the classical theorems for the multiplicity of an ideal generalize to this multiplicity\, including mixed multiplicities\, the Rees theorem and the Minkowski inequality and equality. We give proofs which are independent of the theory of volumes and Okounkov bodies for all of our results\, with the one exception being the proof of the Minkowski equality. We do this by interpreting the multiplicity of graded families of $m_R$-primary ideals as an intersection product on the family of $R$-schemes which are obtained by blowing up $m_R$-primary ideals in $R$. \n

SUMMARY:Quantum topology from dynamics
DESCRIPTION:Member Seminar \nSpeaker: Sunghyuk Park\, CMSA \nTitle: Quantum topology from dynamics \nAbstract: Dynamics studies the long-term behavior of systems that evolve over time\, such as the famous Lorenz system.\nQuantum topology\, by contrast\, studies knots and low-dimensional manifolds through invariants that are usually constructed using representation-theoretic tools. In this talk\, I will explain how quantum invariants of knots and 3-manifolds can be recovered from the dynamics of certain three-dimensional flows. Time permitting\, I will also explain how this new bridge arises from ideas in topological string theory. \n

SUMMARY:Swampland and our Universe
DESCRIPTION:Swampland and our Universe \nDates: April 15–16\, 2026 \nLocation: Harvard CMSA\, Room G10\, 20 Garden Street\, Cambridge MA \nThe swampland program has inspired a range of new ideas in both cosmology and neutrino physics. This workshop brings together experts in neutrino physics\, dark energy\, dark matter\, early-universe cosmology\, and string theory to share insights on these developments and to discuss current and future experimental tests. \nRegister Online \nSpeakers \n\nIgnatios Antoniadis\, IAS\, Princeton\nAlek Bedroya\, Princeton\nMike Boylan-Kolchin\, UT Austin\nRaphael Flauger\, UC San Diego\nM.C. Gonzalez-Garcia\, ICREA U. Barcelona & YITP Stony Brook\nMustapha Ishak-Boushaki\, UT Dallas\nMarc Kamionkowski\, Johns Hopkins\nMiguel Montero\, Institute of Theoretical Physics\, Madrid\nGeorges Obied\, U Chicago\nMatt Reece\, Harvard\n\nOrganizers: Luis Anchordoqui (CUNY Lehman College)\, Sonia Paban (Harvard Physics)\, and  Cumrun Vafa (Harvard Physics) \n  \nSchedule \nWednesday\, Apr. 15\, 2026 \n8:00–9:00 am\nBreakfast \n9:00–10:00 am\nMark Kamionkowski\, Johns Hopkins –Dark-matter dynamics and new physics \nAbstract: Galactic halos that are spherical\, stationary\, and composed of collisionless dark matter are easy to describe mathematically. If dark matter decays or interacts or there is some departure from equilibrium or time evolution of the system\, all bets are off. In this case costly N-body simulations are required. If\, however\, one retains the assumption of spherical symmetry\, these systems can be evolved numerically with a far simpler algorithm that is easily coded run in a matter of minutes on a laptop\, rather than a day on a supercomputer. I will describe this approach and illustrate with simulations of self-interacting dark matter\, decaying dark matter (with and without anisotropic velocity distributions\, supermassive-black-hole growth\, tidal stripping\, mixed SIDM/CDM models. Come prepared with your own non-standard dark-matter model; we’ll see if we can simulate it during the talk! \n10:00–10:30 am\nCoffee Break \n10:30–11:30 am\nRaphael Flauger\, UC San Diego \n11:30 am–1:00 pm\nLunch Break (catered) \n1:00–2:00 pm\nAlek Bedroya\, Princeton \n2:00–2:30 pm\nCoffee Break \n2:30–3:30 pm\nMustapha Ishak-Boushaki\, UT Dallas: Persistent and serious challenge to the ΛCDM throne: Evidence for dynamical dark energy rising from combinations of different types of datasets \nAbstract: We derive multiple constraints on dark energy and compare dynamical dark energy models with a time-varying equation of state (w0waCDM) versus a cosmological constant model (LCDM). We use Baryon Acoustic Oscillation (BAO) from DESI and DES\, Cosmic Microwave Background from Planck with and without lensing from Planck and ACT (noted CMBL and CMB\, respectively)\, supernovae(SN)\, and cross-correlations between galaxy positions and galaxy lensing from DES. We use pairs or triplets of datasets where we exclude one type of dataset each time and categorize them as “NO SN”\, “NO CMB” and “NO BAO” combinations. In all cases\, we find that the combinations favor the w0waCDM model over LCDM\, with significance ranging from 2.0 to 3.0-sigma. The persistence of this pattern across various dataset combinations even when any of the datasets is excluded supports an overall validation of this trending result regardless of any specific dataset. Next\, we use larger combinations of these datasets after verifying their mutual consistency within the w0waCDM model. We find combinations that give robust significance levels\, with DESI+DESY6BAO+CMBL+SN giving 3.4-sigma. In sum\, while we need to remain cautious\, the trend and pattern of these results beyond any single type of dataset and their associated systematics presents a compelling overall portrait not in favor of the LCDM and constitutes a serious challenge to the model’s reign. A few other cosmological results will be provided. \n3:30–4:00 pm\nCoffee Break \n4:00–5:00 pm\nGeorge Obied\, U Chicago \n   \nThursday\, Apr. 16\, 2026 \n8:00–8:30 am\nBreakfast \n8:30–9:30 am\nMC Gonzalez-Garcia\, ICREA U. Barcelona\, YITP Stony Brook \n9:30–10:00 am\nCoffee Break \n10:00–11:00 am\nMiguel Montero\, IFT\, Madrid – Neutrinos and B-L symmetry in the Dark Dimension scenario \nAbstract: The Dark Dimension proposes the existe of a micrometer-sized large extra dimension\, whose size is tied to the observed small vacuum energy. I will review the scenario\, and then discuss how to embed the B-L global symmetry of the SM\, focusing on one possibility which leads to an explanation of the observed coincidence between neutrino mass scale and the  vacuum energy scale\, while leading to 3 light species of right-handed neutrinos. I will also briefly discuss potential opportunities for detection of the resulting neutrino oscillations. \n11:00–11:30 am\nCoffee Break \n11:30 am–12:30 pm\nIgnatios Antoniadis\, IAS\, Princeton – Searching for the dark dimension in neutrino experiments \nAbstract: Micron size extra dimensions offer a possibility to explain the smallness of neutrino masses if the right-handed neutrino propagates in the higher dimensional bulk. I will discuss the theoretical framework and the experimental signatures of this proposal in present and future experiments of KATRIN prototype\, aiming to measure the magnitude of neutrino masses and to search for extra sterile-type species. \n12:30–1:30 pm\nLunch Break (catered) \n1:30–2:30 pm\nMike Boylan-Kolchin\, UT Austin – Galaxies as Tracers of the Matter Density Field \nAbstract: Galaxy formation is often (rightly) thought of as involving a complex interplay of messy astrophysical processes\, but it also traces the nonlinear evolution of the matter density in the Universe. Remarkably\, it appears that properties of this nonlinear field are intimately connected to properties of the initial linear fluctuations and some basic physics of dark matter interactions. I will explore some of these connections\, with applications that include the surprisingly fast evolution of early galaxy formation as revealed by JWST and properties of the lowest-mass dark matter clumps capable of hosting galaxies in the local Universe.\n2:30–3:00 pm\nCoffee Break \n3:00–4:00 pm\nMatt Reece\, Harvard – Axions from String Theory\, and String Theory from Axions \nAbstract: String theory compactifications contain the right ingredients to produce axion fields that might solve the Strong CP problem or contribute to dark matter or dynamical dark energy in our universe. After briefly reviewing some of these ingredients\, I will frame the inverse question: suppose that an axion is discovered\, and its decay constant is measured in an experiment. Could this help us to locate ourselves in the string landscape? In particular\, I will discuss how an axion could give us clues about the fundamental string scale and the scale of supersymmetry breaking. \n  \n

SUMMARY:Interpolation for points in $\mathbb{P}^N\, N\geq 2$
DESCRIPTION:Algebra Seminar \nSpeaker: Dipendranath Mahato\, Tulane University \nTitle: Interpolation for points in $\mathbb{P}^N\, N\geq 2$ \nAbstract: Interpolation problems study hypersurfaces in projective space passing through prescribed sets of points. Classically\, one asks how many independent conditions a collection of points imposes on hypersurfaces of a fixed degree\, a question that can be studied algebraically via homogeneous ideals and their Hilbert functions. In this talk\, I will begin with the classical interpolation problem for reduced points and introduce the algebraic framework used to study it. I will then move to fat point schemes\, where points are assigned multiplicities and hypersurfaces are required to vanish to higher order. In this setting\, interpolation problems naturally lead to symbolic powers of ideals and containment relations between symbolic and ordinary powers. I will conclude by discussing open questions\, including potential connections between interpolation problems and combinatorial structures such as matroids.

SUMMARY:Mathematics and Biology II: Mathematics and Science of Behavior
DESCRIPTION:Mathematics and Biology II: Mathematics and Science of Behavior \nDates: April 27 – May 1\, 2026 \nLocation: Harvard CMSA\, Room G10\, 20 Garden Street\, Cambridge MA \n\n\nThis meeting will explore the emerging mathematics and science of embodied cognition—the idea that behavior arises not solely from the brain but through the dynamic interaction of brain\, body\, and environment. Understanding how animals sense\, move\, decide\, and coordinate\, from individual sensorimotor loops to collective dynamics\, demands mathematical frameworks that integrate geometry\, dynamics\, stochastic processes\, control theory\, and multiscale physics. The meeting will bring together experimentalists studying behavior across species with theorists and engineers building mathematical models and bio-inspired machines\, to identify shared principles of adaptive behavior. \n\n\nCo-organizers: L. Mahadevan (Harvard)\, Francesco Mori (Harvard CMSA)\, Venkatesh Murthy (Harvard) \nRegister to attend in-person \n  \nSpeakers \n\nPulkit Agrawal\, MIT\nKristin Branson\, HHMI\nAntonio C. Costa\, Sorbonne University/Paris Brain Institute\nNoah Cowan\, Johns Hopkins University\nRobert Datta\, Harvard Medical School\nBen de Bivort\, Harvard University\nOfer Feinerman\, Weizmann Institute of Science\nDeborah Gordon\, Stanford University\nAlbert Kao\, UMass Boston\nAnn Kennedy\, Scripps Research Institute\nHungtang Ko\, Tufts University\nGeorge Lauder\, Harvard University\nBence Ölveczky\, Harvard University\nKirstin Petersen\, Cornell University\nPavan Ramdya\, EPFL\nElizabeth Tibbetts\, University of Michigan\nRobert Wood\, Harvard University\n\n  \n\nSchedule  \nMonday\, Apr. 27\, 2026 \n9:00–9:30am: Breakfast \n9:30–10:15 am: Deborah Gordon\, Stanford University\nTitle: The dynamics of collective behavior in changing environments\nAbstract: Collective behavior operates without central control\, using interactions among participants adjust to changing conditions. There is enormous diversity in the dynamics of collective behavior\, including in the rate of response to conditions\, in feedback regimes that set whether interactions stimulate or inhibit activity\, and the extent of centralization or modularity of information flow.  An ecological perspective suggests how this diversity of collective behavior reflects the dynamics of the environment\, including its stability\, the ratio of resources spent to resources gained\, and the distribution of resources in time and space.\nAs examples\, I will discuss field studies and modelling of the regulation of foraging behavior in two species of ants\, Harvester ant colonies in the desert regulate foraging to manage high costs\, in water loss\, to obtain scattered and stable resources. They use a centralized system\, with the default to remain inactive unless stimulated\, that is slow to adjust foraging activity. In contrast\, the turtle ant colonies form trail networks in the canopy of the tropical forest\, in unstable conditions where activity costs are low\, to find and collect ephemeral and patchy resources. They use a highly modular system\, with the default to sustain activity unless inhibited\, that can rapidly adjust trail networks to changing resources and conditions. \n10:15–10:30 am: Discussion \n10:30–11:00 am: Tea Break \n11:00–11:45 am: Hungtang Ko\, Tufts University \n11:45 am–12:00 pm: Discussion \n12:00–1:00 pm: Catered Lunch \n1:00–1:45 pm: Albert Kao\, UMass Boston \n1:45–2:00 pm: Discussion \n2:00–2:45 pm: Ann Kennedy\, Scripps Research Institute\nTitle: Neural mechanisms that gate the expression of motivated behaviors \n2:45–3:00 pm: Discussion \n3:00–4:30 pm: Break \n4:30–5:30 pm: CMSA Colloquium: Ofer Feinerman\, Weizmann Institute of Science \n  \nTuesday\, April 28\, 2026 \n9:00 –9:30 am: Breakfast \n9:30–10:15 am: Ben de Bivort\, Harvard University\nTitle: Bayesian Inference on biophysical models of connectomes \nAbstract: Recent progress in connectomics has opened new frontiers for understanding the underlying principles of neural circuits. By leveraging high-resolution maps of synaptic connections\, computational models can simulate neural dynamics with unprecedented detail. However\, it remains challenging to parsimoniously integrate circuit activity data with connectomic information to make biological in- sights. We propose a Bayesian framework as a principled method for bringing to bear existing data\, enabling uncertainty quantification for inferring parameters of interest\, as well as for predicted circuit outputs. To demonstrate this approach\, we implement a simple spiking neuron model using leaky- integrate-and-fire dynamics in the Drosophila olfactory circuit\, incorporating available firing rate data. We evaluate how models with varying levels of biological detail fit experimental data and examine how training on different subsets of data influences model predictions. \n10:15–10:30 am: Discussion \n10:30–11:00 am: Tea Break \n11:00–11:30 am: Trainee talk \n11:30 am–12:00 pm: Trainee talk \n12:00–1:00 pm: Catered Lunch \n1:00–1:45 pm: Noah Cowan\, Johns Hopkins University\nTitle: Toward a Control Theory for Active Sensing\nAbstract: Active sensing is often defined as “movement for the purpose of sensing.” Here\, I take a different perspective—that active sensing in biological systems is not a distinct class of behaviors\, but rather a set of movement phenomena that arise from a control objective. Biological sensors adapt to persistent stimuli\, acting like high-pass filters that tend to block “DC.” Such “change-detecting” sensors can support efficient coding with a high dynamic range\, and in engineering\, bio-inspired event cameras are similar: they transmit information only when a pixel changes and\, as such\, are extremely fast and make efficient use of bandwidth for the right applications. However\, such “AC” sensors pose technical challenges for control. Specifically\, event-like biological sensors can cause a nonlinear system (1) to lose local linear observability\, and (2) to become impossible to stabilize about an equilibrium point (Biswas\, Sontag\, Cowan\, Eur J Control\, 2025). Active sensing behaviors must emerge for stable control\, even in the somewhat paradoxical setting where the task-level goal is to remain stationary. Here\, I will discuss my lab’s progress in analyzing how animals use active sensing behaviors to format sensory information\, enhancing observability and control. I will also present our efforts to formalize controller synthesis with event-like sensors. \n1:45–2:00 pm: Discussion \n2:00–2:45 pm: Robert Datta\, Harvard Medical School \n2:45–3:00 pm: Discussion \n3:00–3:30 pm: Break \n3:30–4:15 pm: TBD \n4:15–4:30: Discussion \n  \nWednesday\, April 29\, 2026 \n9:00 –9:30 am: Breakfast \n9:30–10:15 am: Kristin Branson\, HHMI \n10:15–10:30 am: Discussion \n10:30–11:00 am: Tea Break \n11:00–11:30 am: Trainee talk \n11:30 am–12:00 pm: Trainee talk \n12:00–1:00 pm: Catered Lunch \n1:00–1:45 pm: Bence Ölveczky\, Harvard University \n1:45–2:00 pm: Discussion \n2:00–2:45 pm: Pavan Ramdya\, EPFL\nTitle: Towards fly-inspired legged robots\nAbstract: I will discuss our efforts to build biologically-inspired legged robots using behavioral measurements\, neuromechanical simulations\, and anatomical studies of Drosophila melanogaster. \n2:45–3:00 pm: Discussion \n3:00–3:30 pm: Break \n3:30–4:15 pm: TBD \n4:15–4:30: Discussion \n  \nThursday\, April 30\, 2026 \n9:00 –9:30 am: Breakfast \n9:30–10:15 am: Pulkit Agrawal\, MIT \n10:15–10:30 am: Discussion \n10:30–11:00 am: Tea Break \n11:00–11:30 am: Trainee talk \n11:30 am–12:00 pm: Trainee talk \n12:00–1:00 pm: Catered Lunch \n1:00–1:45 pm: Elizabeth Tibbetts\, University of Michigan\nTitle: What paper wasps can teach us about the evolution of animal minds\nAbstract: Why do animals differ in their cognitive abilities? Some animals fail at apparently simple tasks\, while others have a remarkable capacity to collect\, retain\, and use information from the environment to guide their behavior. Although paper wasps brains are smaller than a grain of rice\, Tibbetts will show that wasps can perform seemingly complex behaviors like individual face recognition\, transitive inference\, social eavesdropping\, and concept learning. She will also describe experiments that take advantage of natural variation in behavior within and among wasp species to test how social interactions shape the development and evolution of cognitive abilities. \n1:45–2:00 pm: Discussion \n2:00–2:45 pm: Robert Wood\, Harvard University\nTitle: The Mechanical Side of Artificial Intelligence\nAbstract: Artificial Intelligence research typically focuses on perception\, learning\, and control methods to enable autonomous agents\, including robots\, to make and act on decisions in real-world scenarios. However\, even the most capable AI without a well-designed physical structure is of minimal use for canonical robotics tasks. Our research is focused on the design\, mechanics\, materials\, and manufacturing of novel robot platforms that make perception\, control\, or action easier or more robust for natural\, unstructured\, and often unpredictable environments. Key principles in this pursuit include bioinspired designs\, smart materials for novel sensors and actuators\, and the development of multi-scale\, multi-material manufacturing methods. This talk will illustrate this philosophy by highlighting the creation of three classes of robots with unique hardware challenges: bioinspired microrobots\, soft-bodied robots for manipulation\, and robots for interacting with delicate marine life. \n2:45–3:00 pm: Discussion \n3:00–3:30 pm: Break \n3:30–4:15 pm: TBD \n4:15–4:30 pm: Discussion \n  \nFriday\, May 1\, 2026 \n9:00–9:30 am: Breakfast \n9:30–10:15 am: George Lauder\, Harvard University \n10:15–10:30 am: Discussion \n10:30–11:00 am: Tea Break \n11:00–11:45 am: Antonio C.

Our work spans scales and mechanisms\, from behaviors encoded in robot morphology to collective behaviors that emerge through physical coupling and stigmergic coordination when many robots operate in shared environments. Many of these principles are inspired by biological systems\, including our studies of construction and aggregation in honey bees and subterranean and mound-building termites. In this talk\, I will present examples from our lab\, including soft robots that exploit viscous fluid–structure interactions for articulated control\, microrobots that leverage magnetic and hydrodynamic interactions to produce a range of collective behaviors\, and entangled robotic matter that achieves cohesive motion through transient physical entanglement. Together\, these systems illustrate how intelligence can be distributed across morphology\, interactions\, and shared substrates\, enabling scalable and robust robot collectives. \n2:45–3:00 pm: Discussion \n3:00–3:30 pm: Break \n3:30–4:15 pm: TBD \n4:15–4:30 pm: Discussion

SUMMARY:Transcendental Epsilon Multiplicity via Divisor Volumes
DESCRIPTION:Algebra Seminar \nSpeaker: Sudipta Das\, Tata Institute of Fundamental Research \nTitle: Transcendental Epsilon Multiplicity via Divisor Volumes \nAbstract:  In this talk\, our goal is to establish a structural bridge between asymptotic commutative algebra and transcendence theory to show that there exists an ideal in a Noetherian local ring whose epsilon multiplicity is transcendental. By equating the local-cohomological definition of epsilon multiplicity to a global divisorial volume integral on a projective bundle\, we apply Baker’s theorem on linear forms in logarithms to prove that the resulting arithmetic invariant falls strictly outside the field of algebraic numbers. This talk is based on collaborative work with Vinh Pham and Stephen Landsittel. \n

SUMMARY:Stable Homotopy Theory and Arithmetic Geometry
DESCRIPTION:Stable Homotopy Theory and Arithmetic Geometry \nDates: Feb 15–May 15\, 2027 \nLocation: Harvard CMSA\, 20 Garden St\, Cambridge MA \nThis program will focus on interactions between stable homotopy theory and arithmetic geometry. In recent years\, ideas from homotopy theory have begun to play an important role in areas such as p-adic cohomology\, prismatic methods\, and aspects of the Langlands program\, while techniques from arithmetic geometry have led to new insights and computations in chromatic homotopy theory. Despite this growing overlap\, researchers in the two areas often use different languages and tools. A central goal of the program is to make these ideas more accessible across fields and to encourage collaborations around shared problems. \nThe program will run from February 15 to May 15 and will be built around research and informal collaboration. It will begin with a short introductory bootcamp\, followed by two focused workshops (one near the start and one toward the end)\, a weekly seminar with broadly accessible talks\, and a weekly open-problem session. Most of the time will be left open for discussion and joint work among participants\, aiming to spark new projects and longer-term connections between the two communities. \nThe program will include: \n(1) a bootcamp during the week Feb. 22–26\, consisting of introductory lectures on both subjects;\n(2) two research workshops—one during Mar. 1–5 and one during May 3–7—highlighting current developments\, especially those at the interface of the two areas;\n(3) a weekly seminar featuring talks of broad relevance to participants; and\n(4) a weekly open-problem seminar aimed at proposing and developing collaborative research directions\, both for the duration of the program and beyond. \nRegister Online \n  \nOrganizers: Tomer Schlank (UChicago)\, Jared Weinstein (Boston University)\, Mark Kisin (Harvard)\, Jeremy Hahn (MIT)\, Lucas Mann (Münster)
