报告题目: On the S-duality conjecture of Vafa-Witten III: Proof of the S-duality conjecture for K3 surfaces

报告人：蒋云峰 教授（堪萨斯大学）

报告时间：2020年7月15日上午9:00

报告内容：In the second talk we have defined twisted Vafa-Witten invariants for the Langlands dual gauge group SU(r)/Z_r. In this talk we will formulate a mathematical conjecture of the S-duality conjecture, and we will prove the formulation  for projective planes in rank two  and K3 surfaces for prime ranks.

报告人简历：Prof. Yunfeng Jiang received his Ph.D in mathematics from University of British Columbia (UBC).  Before joining University of Kansas, he worked as a postdoc at University of Utah and Imperial College London.  His main research interests are the general area of  Algebraic Geometry and mathematics physics, especially in the area of Gromov-Witten and Donaldson-Thomas theory, with relations to birational geometry, geometric representation theory, combinatorics and mirror symmetry.
