Wall-Crossing in Genus Zero K-theoretic Landau-Ginzburg Theory
Abstract
For a Fermat quasi-homogeneous polynomial W, we study a family of K-theoretic quantum invariants parametrized by a positive rational number ε. We prove a wall-crossing formula by showing the generating functions lie on the Lagrangian cone of the permutation-equivariant K-theoretic FJRW theory of W.
