Title: On Axially Symmetric Perturbations of Kerr Black Hole Spacetimes
General Relativity Seminar Speaker: Nishanth Gudapati, Clark University Title: On Axially Symmetric Perturbations of Kerr Black Hole Spacetimes Abstract: The Kerr black hole stability problem is an important open problem in general relativity. In this talk, I will focus on the role of energy methods in the axisymmetric stability of Kerr black hole spacetimes. In particular, I will discuss the construction and the application of a positive Hamiltonian energy for axially symmetric Maxwell and Einstein perturbations of sub-extremal Kerr black hole spacetimes.

Title: Classifying curves on Fano varieties
Algebraic Geometry in String Theory Seminar Speaker: Brian Lehmann (Boston College) Title: Classifying curves on Fano varieties Abstract: How can we understand the set of curves on a Fano variety? One perspective is provided by Geometric Manin's Conjecture, a collection of conjectures with roots in arithmetic and topology.  While I will mention some recent progress, the main focus will be developing a conceptual framework for thinking about our question.

Title: Directed motion in active matter: Frictiotaxis and flocking
Active Matter Seminar Speaker: Ricard Alert, Max Planck Institute for the Physics of Complex Systems Title: Directed motion in active matter: Frictiotaxis and flocking Abstract: A key feature of active matter is its ability to move directionally, both as individual particles and collectively. I will discuss two examples of directed motion: one in cell migration, and one in collections of self-propelled colloids. First, I will show that cells lacking cell-substrate adhesions migrate along friction gradients. We call this phenomenon frictiotaxis, which is a new type of cell guidance. Second, I will present a new mechanism for flocking whereby self-propelled particles can align and move collectively despite turning away from each other.

Title: Contract Design in Combinatorial Settings
CMSA Member Seminar Speaker: Tomer Ezra (Harvard CMSA) Title: Contract Design in Combinatorial Settings Abstract: We study two combinatorial settings of the contract design problem, in which a principal wants to delegate the execution of a costly task. In the first setting, the principal delegates the task to an agent that can take any subset of a given set of unobservable actions, each of which has an associated cost. The principal receives a reward which is a combinatorial function of the actions taken by the agent. In the second setting, we study the single-principal multi-agent contract problem, in which the principal motivates a team of agents to exert effort toward a given task. We design (approximately) optimal algorithms for both...

Title: LILO: Learning Interpretable Libraries by Compressing and Documenting Code
New Technologies in Mathematics Seminar Speaker: Gabe Grand, MIT CSAIL and Dept. of EE&CS Title: LILO: Learning Interpretable Libraries by Compressing and Documenting Code Abstract: While large language models (LLMs) now excel at code generation, a key aspect of software development is the art of refactoring: consolidating code into libraries of reusable and readable programs. In this paper, we introduce LILO, a neurosymbolic framework that iteratively synthesizes, compresses, and documents code to build libraries tailored to particular problem domains. LILO combines LLM-guided program synthesis with recent algorithmic advances in automated refactoring from Stitch: a symbolic compression system that efficiently identifies optimal lambda abstractions across large code corpora. To make these abstractions interpretable, we introduce an auto-documentation (AutoDoc) procedure that...
