$K$ -theoretic wall-crossing formulas and multiple basic hypergeometric series

Ryo Ohkawa, Jun'ichi Shiraishi

We study $K$ -theoretic integrals over famed quiver moduli via wall-crossing phenomena. We study the chainsaw quiver varieties, and consider generating functions defined by two type…

Residue formula for flag manifold of type $A$ from wall-crossing

Ryo Ohkawa

We consider equivariant integrals on flag manifolds of type $A$ . Using a computational method inspired by the theory of wall-crossing formulas by Takuro Mochizuki, we re-prove resi…
