DESCRIPTION:Speakers: Xiaohan YAN (Sorbonne Université)\n\nThe K-theoreti
 c Gromov-Witten (KGW) theory gives deformation invariants of a complex var
 iety by counting curves. It is related to the more classical Gromov-Witten
  (GW) theory via the Grothendieck-Riemann-Roch theorem. In this talk\, I d
 iscuss the use of abelian/non-abelian correspondence in studying the KGW t
 heory of GIT quotients. It gives a solution of the genus-zero KGW invarian
 ts of flag varieties\, and interacts with structural results like the « q
 uantum » version of Lefschetz theorem and of Serre duality. I also discus
 s potential further applications of the method.\n\nhttps://indico.math.cnr
