Hidden algebraic structures in geometry from quantum field theory

Time：Fri., 4:00-5:00 pm May 26, 2023

Venue：Zoom Meeting ID: 271 534 5558 Passcode: YMSC ; Lecture Hall, 3rd Floor Jin Chun Yuan West Bldg.

Speaker：Du Pei University of Southern Denmark

Speaker

Du Pei is currently an associate professor of quantum mathematics at the University of Southern Denmark. He obtained his Ph.D. in theoretical physics in 2016 from Caltech. His main research interests concern the geometric, algebraic and categorical properties of quantum field theory.

Abstract

The existence of quantum field theories in higher dimensions predicts many hidden algebraic structures in geometry and topology. In this talk, I will survey some recent developments where such algebraic structures lead to new insights into 1) the quantization of moduli spaces of Higgs bundles, 2) the categorification of quantum invariants of 3-manifolds, and 3) novel types of TQFTs in four dimensions.

Modern Mathematics Lecture Series Representation theory and a little bit of quantum field theory
Abstract：One of the central foci of representation theory in the 20th century was the representation theory of Lie algebras, starting with finite dimensional algebras and expanding to a rich, but still mysterious infinite dimensional theory. In this century, we realized that this was only one special case of a bigger theory, with new sources of interesting non-commutative algebras whose repres...
