-theoretic quasimap wall-crossing
Ming Zhang, Yang Zhou
In this paper, we prove a K-theoretic wall-crossing formula for -stable quasimaps for all GIT targets in all genera. It recovers the genus-0 K-theoretic toric mirror theorem by…

Verlinde/Grassmannian Correspondence and Rank 2 -wall-crossing
Yongbin Ruan, Ming Zhang
Motivated by Witten's work (arXiv:hep-th/9312104), we propose the Verlinde/Grassmannian correspondence which relates the GL Verlinde numbers to the K-theoretic quasimap invariants…

The level structure in quantum K-theory and mock theta functions
Yongbin Ruan, Ming Zhang
This is the first in a sequence of papers to develop the theory of levels in quantum K-theory and study its applications. Our main results in this paper are toric mirror theorems f…
