Colloquium Speaker: Mehran Kardar, MIT Title: Life on a Noisy Seascape: Extinction, Growth, and Diversity Abstract: Populations and communities rarely evolve in static environments; their fitness landscapes fluctuate across space and time, forming what may be called a noisy seascape. This talk examines how such variability modifies classical models of population dynamics and community stability. Beginning from the […] |

AI for the Working Mathematician Speaker: Harold Williams, USC Title: An Informal Introduction to Formal Proofs Abstract: In this talk we will give an introduction to Lean, a programming language adapted to expressing and verifying proofs. Lean and its flagship library, mathlib, have been the focus of a dedicated user community for about a decade, […] |

Geometry and Mathematical Physics Seminar Speaker: Tobias Ekholm, Uppsala Title: Skein valued curve counts and associatives Abstract: We consider Lagrangians in the cotangent bundle of a 3-manifold that give branch covers the 0-section. A circle bundle over the cotangent bundle that degenerates over the Lagrangian gives an A_n-fibration over the base 3-manifold. We equip this A_n […] |

Member Seminar Speaker: Aaron Landesman Title: Painlevé VI: the search for canonical representations Abstract: In 1902, Painlevé classified second order differential equations whose only movable singularities are poles, thereby obtaining the six Painlevé equations. Algebraic solutions to Painlevé's sixth equation correspond to canonical triples of 2 by 2 complex matrices. One can alternatively view these […] |

CMSA Special Seminar Speaker: Michael Brenner Title: A physical interpretation of recent singularity theorems Abstract: We present a physical interpretation of recent mathematical proofs (Córdoba and Martínez-Zoroa; Buckmaster and Apogee; OpenAI) for singularity formation in nonlinear partial differential equations with smooth forcing. In our formulation, singularity formation is driven by a forward in time process whereby […]

Colloquium Speaker: Subhabrata Sen, Harvard Statistics Title: Spectral Methods for signal recovery in multi-modal problems Abstract: Motivated by multi-modal estimation, we will study a multi-view spiked random matrix model in which several noisy matrix observations contain correlated spikes. We will introduce a new spectral method for signal recovery in this setting and characterize the behavior […] |

CMSA Q&A Seminar Speaker: Shaoyun Bai, MIT Title: What is a virtual fundamental cycle? (ICM Series: On the work of John Pardon) Abstract: One of Pardon’s important contribution to symplectic topology is a new approach to constructing virtual fundamental cycles/chains for moduli spaces of pseudo-holomorphic maps. As a former PhD student of John, my own […] |

Member Seminar Speaker: Bowen Yang, Harvard CMSA Title: Quantum Cellular Automata and K theory Abstract: I’ll explain a new class of Omega spectrum originating from the study of locality preserving quantum dynamics. Using it, I’ll explain the so-called “open cone principle” which bridges lattice models at thermodynamic limits with continuous field theory. As an application, […]

AI for the Working Mathematician Speaker: Jordan Ellenberg, University of Wisconsin-Madison Title: Large Hypercubes Abstract: I'll talk about this paper: Bruhat intervals that are large hypercubes <arxiv.org/abs/2601.01235> in which we use a tool from Google, AlphaEvolve, to discover unexpected combinatorial structures inside the symmetric group (to be precise, a large hypercube in the Bruhat order.) I'll […] |

AI for the Working Mathematician Speaker: Lauren Williams, Harvard Title: First Proof Batch 3: Mathematicians putting AI to the test Abstract: First Proof is an initiative that aims to obtain a nuanced, objective assessment about the capabilities of large language models to prove specified mathematical statements. I will report on the results of First Proof's third […] |
