Colloquium Speaker: Anar Akhmedov, University of Minnesota Title: The Geography of Symplectic 4-Manifolds Abstract: The symplectic geography problem, originally posed by J. McCarthy-J. Wolfson and R. Gompf, asks which ordered pairs of nonnegative integers are realized as (\chi(X),c_1^2(X)) for a symplectic 4-manifold X, where \chi(X)=(e(X)+\sigma(X))/4. In this talk, we will address the geography of simply […]
Joint Math/CMSA Geometry and Quantum Theory Seminar Speaker: Kason Kunkelmann, Harvard Title: A Rigorous Construction of the Free Quantum Field Abstract: In this talk we will build on last week’s discrete intuition and rigorously construct our first continuum quantum field theory: the free field. Following Chapter three of Chatterjee’s notes, we will realize it as a Gaussian […]
New Technologies in Mathematics Seminar Speaker: Xinjie He, UCLA Title: The IEANTN Project: Automation and Mathematical Understanding Abstract: Explicit analytic number theory combines conceptual arguments with extensive bookkeeping and numerical computation, often drawing on long chains of results across many papers. The Integrated Explicit Analytic Number Theory Network (IEANTN) aims to organize this literature into […]
AI for the Working Mathematician Speaker: Tristan Buckmaster, NYU Title: A 'Deep Blue-Kasparov moment for mathematics' Abstract: In this talk I will describe recent work with Levent Alpöge proving the blow-up for smooth solutions to the incompressible Euler equations and the broader implications that such results have of the study of mathematics.
CMSA/Tsinghua Math-Science Literature Lecture Date: Thursday, October 29, 2026 Time: 9:00 - 10:30 am ET Location: online via Zoom Webinar Please register to attend. Zoom Webinar registration Speaker: Peng Shan, Tsinghua University Title: Bridging affine vertex algebras and affine Springer fibres Abstract: In this talk, I would like to explain a program which […]
Geometry and Mathematical Physics Seminar Speaker: Elliott Gesteau (MIT & CMSA) Title: Worldsheets, baby universes, and asymptotic representation theory Abstract: The string worldsheet can be reinterpreted as a baby universe field theory, a formalism first introduced by Coleman, Giddings and Strominger and more recently revived by Marolf and Maxfield to deal with third quantization in […]
Member Seminar Speaker: Bowen Yang Title: Poincaré Duality in Quantum Error-Correcting Codes Abstract: Quantum information is fragile, and one of the main tools for protecting it is a family of error-correcting codes called stabilizer codes. These codes have a second life as exactly solvable models of quantum matter: the code space is the vacuum state […]
Freedman Seminar Speaker: Michael Freedman, Harvard CMSA Title: The geometry of the Bing Involution Abstract: I’ll discuss a new sharper proof, joint with Mike Starbird that precisely quantifies the stretching necessary for Bing’s wild involution on S^3.
Doing Mathematics with AI Agents Date: Saturday, October 31, 2026 Time: 9:00–5:00 pm ET Location: Zimmer Hall (Science Center), 1 Oxford Street, Cambridge MA This is a one day workshop for Boston-area mathematics faculty to work with AI agents in a collaborative environment (designed by Andrew Sutherland) supported by computational infrastructure and formalization tools. This […]
Joint Math/CMSA Geometry and Quantum Theory Seminar Speaker: Tobias Schmidt, Harvard CMSA Title: The free field and the Fock space Abstract: Last time we defined a stochastic process on tempered distributions corresponding to the euclidean action of the free field. In this talk, we begin with verifying the Markov property. Next, we will show a […]
CMSA Q&A Seminar Speaker: Wes Cain, Harvard Title: Can Math Mend a Broken Heart? Abstract: I will discuss an abnormal cardiac rhythm known as T-wave alternans, and a simple feedback control method (time-delay autosynchronization, TDAS) that has been used successfully to suppress alternans experimentally. Variants of TDAS have been used for chaos control and prevention […]
New Technologies in Mathematics Seminar Speaker: Yasaman Bahri (Google DeepMind) Title: On the emergence of representational geometry from the statistics of natural language Abstract: Large language models organize their internal representations into rich geometric structures that mirror the concepts of natural language. For example, categorical concepts often map to linear directions, while words and phrases […]
