Matrix Model and Refined Wall-Crossing Formula

Abstract

In this paper, we show how to get matrix models corresponding to the refined BPS states partition functions of ${\mathbb{C}}^3$, resolved conifold and ${\mathbb{C}}^3/{\mathbb{Z}}_2$ by inserting the identity operator at a proper position in the fermionic expression of the refined BPS states partition functions.
