Quasimap theory is a curve counting theory which is a generalization of Gromov-Witten theory for GIT quotients. It can be further extended to GLSM that describe critical loci in GIT quotients. It is known that GIT stability wall-crossing implies relations for the corresponding quasimaps, such as Landau-Ginzburg/Calabi-Yau correspondence and crepant transformation conjecture. In the talk I will show how to extend these wall-crossing results to the setting of K-theoretic quasimaps.


Will be following by lunch.
