DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGSAGS/21/">
 Multiplicative Quantum Cobordism Theory</a>\nby Irit Huq-Kuruvilla (UC Ber
 keley) as part of American Graduate Student Algebraic Geometry Seminar\n\n
 \nAbstract\n$K$-theoretic Gromov-Witten invariants were proposed by Kontse
 vich in the 80s\, and the foundations were developed by YP Lee in 1999. I 
 will introduce a modified form of these invariants obtained by twisting th
 e virtual structure sheaf by an arbitrary characteristic class of the tang
 ent bundle of the moduli space of stable maps\, and state a formula relati
 ng the generating function for these invariants to the unmodified ones. I'
 ll also discuss how these invariants can be used to define Gromov-Witten i
 nvariants valued in other complex-oriented cohomology theories\, the unive
 rsal example of which is cobordism theory. This talk is based on work from
  https://arxiv.org/abs/2101.09305.\n
