SUMMARY:A Rigorous Construction of the Free Quantum Field
DESCRIPTION:Joint Math/CMSA Geometry and Quantum Theory Seminar \nSpeaker: Kason Kunkelmann\, Harvard \nTitle: A Rigorous Construction of the Free Quantum Field \nAbstract: 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 random field in Euclidean spacetime\, prove that it has the Markov property in time\, and then use the procedure outlined in previous lectures to get its Hilbert space and Hamiltonian.

SUMMARY:The IEANTN Project: Automation and Mathematical Understanding
DESCRIPTION:New Technologies in Mathematics Seminar \nSpeaker: Xinjie He\, UCLA \nTitle: The IEANTN Project: Automation and Mathematical Understanding \nAbstract: 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 a living network whose dependencies and supporting evidence are explicit. \nIn this talk\, I will discuss how we redesigned IEANTN from its 1.0 version\, which put everything in a single Lean repository that was hard to maintain and rebuild as auto-formalization produces increasingly large proofs\, to its current 2.0 version\, which solves this problem by separating readable mathematical statements from verified proofs and recording different levels of justification. \nFinally\, I will discuss what we hope to automate and what we want to understand ourselves. By organizing the literature into a network\, we hope to make the mathematical ideas and relationships easier to see\, and leave the detailed bookkeeping to machines. \n

SUMMARY:A 'Deep Blue-Kasparov moment for mathematics'
DESCRIPTION:AI for the Working Mathematician \nSpeaker: Tristan Buckmaster\, NYU \nTitle: A ‘Deep Blue-Kasparov moment for mathematics’ \nAbstract: 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.

SUMMARY:Worldsheets\, baby universes\, and asymptotic representation theory
DESCRIPTION:Geometry and Mathematical Physics Seminar \nSpeaker: Elliott Gesteau (MIT & CMSA) \nTitle: Worldsheets\, baby universes\, and asymptotic representation theory \nAbstract: 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 quantum gravity. In this talk\, I will discuss this reinterpretation in the context of a particularly simple string worldsheet\, and connect it to foundational results in asymptotic representation theory. \n

SUMMARY:Poincaré Duality in Quantum Error-Correcting Codes
DESCRIPTION:Member Seminar \nSpeaker: Bowen Yang \nTitle: Poincaré Duality in Quantum Error-Correcting Codes \nAbstract: 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 and the “syndromes” behave like excitations that can move freely\, get stuck in place\, or wind around one another. I will show how a little homological algebra packages these excitations into clean mathematical objects\, which we call charge modules. Moreover\, there are natural pairing between different charge modules of complementary degrees sometimes called “braiding”. They actually came from the Poincare duality of the sphere. This is joint work with Błażej Ruba. \n
