Classifying curves on Fano varieties
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesAlgebraic 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 […]
Directed motion in active matter: Frictiotaxis and flocking
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesActive 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. […]

AQFT Lecture Series
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesAQFT Lecture Series Speaker: Chen Wan, Rutgers Newark Title: Some examples of the relative Langlands duality Abstract: In this talk I will discuss some examples of the relative Langlands duality (introduced by Ben-Zvi—Sakellaridis—Venkatesh) for strongly tempered spherical varieties. In some cases, I will introduce a relative trace formula comparison for the models and prove the […]
Contract Design in Combinatorial Settings
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesCMSA 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 […]
AQFT Lecture Series
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesAQFT Lecture Series Speaker: Peng Shan (Tsinghua) Title: Skein algebras and quantized Coulomb branches Abstract: In this talk, we explain how to attach a quantized Coulomb branch in the sense of Braverman-Finkelberg-Nakajima to a compact oriented surface of genus at most one, and compare it to the Kauffman bracket Skein algebra in some special cases. This […]
Strong bounds for arithmetic progressions
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesColloquium Speaker: Raghu Meka (UCLA) Title: Strong bounds for arithmetic progressions Abstract: Suppose you have a set S of integers from {1,2,...,N} that contains at least N / C elements. Then for large enough N, must S contain three equally spaced numbers (i.e., a 3-term arithmetic progression)? In 1953, Roth showed this is the case […]
High order WENO finite difference scheme for Einstein-Yang-Mills equations
VirtualGeneral Relativity Seminar Speaker: Yuewen Chen, Tsinghua University Title: High order WENO finite difference scheme for Einstein-Yang-Mills equations Abstract: In this talk, we will show the convergence analysis of the first-order finite difference scheme for static spherically symmetric $SU(2)$ Einstein-Yang-Mills (EYM) equations. We also construct a new WENO scheme for EYM.

LILO: Learning Interpretable Libraries by Compressing and Documenting Code
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United Stateshttps://youtu.be/ZDMRN0Iyp28 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.
