SUMMARY:A Rigorous Construction of the Free Quantum Field
DESCRIPTION:Joint Math/CMSA Geometry and Quantum Theory Seminar \nSpeaker: Kason Kunkelmann \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:What is a self-concordant barrier function?\, and what is an accelerated first-order algorithm?  (ICM Series: On the work of Yurii Nesterov)
DESCRIPTION:CMSA Q&A Seminar \nSpeaker: Robert M. Freund\, MIT \nTitle: What is a self-concordant barrier function?\, and what is an accelerated first-order algorithm?  (ICM Series: On the work of Yurii Nesterov) \nAbstract: The two most impactful contributions of Nesterov on both theory and computation in optimization are (i) self-concordant barriers for interior-point methods in convex optimization\, and (ii) accelerated first-order methods for convex optimization. My own research in continuous optimization – and indeed my perspective on the field of mathematical optimization — has been profoundly impacted by Nesterov. In this talk I aim to explain these two contributions – self-concordant barriers and accelerated first-order methods – and how they have fundamentally improved optimization both computationally and theoretically. \n  \n  \n

SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Peng Shan\, Tsinghua University
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \nDate: Thursday\, October 29\, 2026 \nTime: 9:00 – 10:30 am ET \nLocation: online via Zoom Webinar \n  \nPlease register to attend.  \nZoom Webinar registration \n  \nSpeaker: Peng Shan\, Tsinghua University \nTitle: Bridging affine vertex algebras and affine Springer fibres \nAbstract: In this talk\, I would like to explain a program which aims to build relationships between affine Springer theory and representations of simple affine vertex algebras. We will discuss some explicit correspondences for admissible levels\, and formulate some new conjectures about representations of simple affine vertex algebras at nonadmissible levels and their associated varieties. This is based on joint work with Dan Xie\, Wenbin Yan and Qixian Zhao. \n  \n \n  \nOrganizers: Dan Freed\, Harvard Math & CMSA and Shing-Tung Yau\, Tsinghua University \n  \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars. \n  \n
