Title: On the quantum K-rings of flag varieties of type A

SpeakerHsian-Hua Tseng (Ohio State University)

Abstract: The quantum $K$-ring of a smooth projective variety $X$, introduced by Givental and YP Lee, is a deformation of the Grothendieck ring of coherent sheaves on $X$ defined using holomorphic Euler characteristics on moduli spaces of stable maps to $X$ (these are $K$-theoretic version of Gromov-Witten invariants). In this talk we discuss some properties of the quantum $K$-rings of $X=Fl_{r+1}$, the variety of complete flags in $C^{r+1}$, including:

  1. a presentation of the quantum $K$-ring;
  2. finiteness of quantum product;
  3. canonical polynomial representatives of Schubert classes.

This is based on joint work in progress with David Anderson and Linda Chen.
