DESCRIPTION:Speaker: Xiaohan Yan\nhosted by Tamas Hausel\nAbstract: The Gro
mov-Witten theory studies enumerative invariants of a projective variety $
X$ through counting nodal curves\, and gives a family of deformed multipli
cation structures on the cohomology of $X$\, known as the quantum cohomolo
gy. For flag variety $X=G/B$\, relations in its quantum cohomology may be
obtained through studying the differential equations solved by the generat
ing function known as the J-function\, which in turn come from the Toda la
ttice system of the Langlands dual group of $G$. In the first part of this
talk\, we review the story above. In the second part of this talk\, we di
scuss how much of it still holds in K-theoretic settings\, where quantum K
-theory will replace quantum cohomology\, and difference equations will re
place differential equations. Quantum K-theory arises naturally in the fra
mework of 3D mirror symmetry\, a duality between mirror holomorphic symple
ctic varieties.
