DESCRIPTION:Speakers: Xinyu  Zhang (Zhejiang University)\nA central theme 
 of modern mathematical physics is the interplay between geometry and super
 symmetric gauge theory. After briefly reviewing the basic framework of Don
 aldson–Witten theory\, we outline a physical framework for its K-theoret
 ic generalization. In this approach\, K-theoretic Donaldson invariants ari
 se as topological correlation functions of 5d N=1 SU(2) super Yang–Mills
  theory with a partial topological twist. Using path-integral methods\, we
  evaluate these invariants explicitly. We also present evidence for new in
 variants appearing at the superconformal point that are independent of Don
 aldson and Seiberg–Witten invariants.\n\n个人简介：Xinyu Zhang is a
  Tenure-track Research Professor at the Zhejiang Institute of Modern Physi
 cs\, Zhejiang University. He earned his B.S. in Physics from Peking Univer
 sity in 2011 and completed his Ph.D. in Physics at Stony Brook University 
 in 2017. From 2017 to 2023\, he conducted postdoctoral research at Rutgers
  University and DESY. His research focuses on various aspects of supersymm
 etric theories and mathematical physics.\nhttps://indico.ihep.ac.cn/event/
