CMSA Q&A Seminar Speaker: Yannai Gonczarowski, Harvard University Question: What do people mean when they say 'the intersection between theoretical computer science and economic theory'?

LILO: Learning Interpretable Libraries by Compressing and Documenting Code

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

https://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.

Geometric construction of toric NCRs

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Algebraic Geometry in String Theory Seminar Speaker: Jesse Huang, University of Alberta Title: Geometric construction of toric NCRs Abstract: The Rouquier dimension of a toric variety is recently shown to be achieved by the Frobenius pushforward of O via coherent-constructible correspondence. From the perspective of noncommutative geometry, this result leads to a geometric construction of toric NCR […]

AQFT Lecture Series Speaker: An Huang (Brandeis) Title: Tate's thesis and p-adic strings Abstract: I shall explain the relation between a family of deformations of genus zero p-adic string worldsheet action and Tate's thesis, which in particular, gives rise to an attempt of physically deriving quadratic reciprocity. I shall then propose a genus one p-adic […]

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

AQFT Lecture Series Speaker: John Francis (Northwestern) Title: Integrating braided categories over 3-manifolds Abstract: I’ll describe a form of factorization homology, which gives an invariant of framed 3-manifolds given as input a rigid braided-monoidal category with duals. More generally, the construction gives an invariant of framed n-manifolds from an E_{n-1}-monoidal category with duals. This construction relies […]

A model for studying the sign problem on quantum computers: Z(3) gauge theory with three fermion flavors in 1+1 dimensions

Virtual

Quantum Matter in Mathematics and Physics Seminar Speaker: Semeon Valgushev (Iowa State University) Title: A model for studying the sign problem on quantum computers: Z(3) gauge theory with three fermion flavors in 1+1 dimensions Abstract: Many properties of quantum field theories can be understood with the help of classical numerical methods. Yet there are several […]

Symmetry in quantum field theory

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

CMSA Member Seminar Speaker: Dan Freed (Harvard Mathematics and CMSA) Title: Symmetry in quantum field theory Abstract: In joint work with Greg Moore and Constantin Teleman we show how ideas and techniques in topological field theory apply to the study of symmetry in quantum field theory. I will discuss how this came about, beginning with […]

AQFT Lecture Series Speaker: Dihua Jiang (U Minnesota) Title: Shalika Periods: Functoriality and Arithmetic Abstract: Shalika periods of automorphic forms were first used by H. Jacquet and J. Shalika (1990) in their construction of global zeta integrals for exterior square L-functions of GL(2n). They were also used by S. Friedberg and H. Jacquet (1993) in […]

Cluster state as a noninvertible SPT phase

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Quantum Matter in Mathematics and Physics Seminar Speaker: Shu-Heng Shao (SUNY Stony Brook) Title: Cluster state as a noninvertible SPT phase Abstract: We will point out a non-invertible symmetry of the ordinary 1+1d Z2xZ2 cluster Hamiltonian. Therefore, the cluster state can be viewed as a non-invertible SPT phase under this fusion category symmetry, which is […]

Monopoles, scattering, generalized symmetries

Virtual

Quantum Matter in Mathematics and Physics Seminar Speaker: Diego Delmastro (Simons Center for Geometry and Physics) Title: Monopoles, scattering, generalized symmetries Abstract: Gauge theory is a very mature subject by now. Surprisingly, some of its symmetries have only been properly understood in the last couple of years. Specifically, such theories typically have a very rich set […]

AQFT Lecture Series Speaker: Tasho Kaletha (University of Michigan) Title: Covers of reductive groups and functoriality Abstract: When studying problems arising from Langlands' functoriality principle, one often encounters groups that are extensions of complex reductive groups by Galois groups, but that do not necessarily satisfy all properties to be L-groups of reductive groups. We will show, […]
