$T^*Gr(k,n)$的辛对偶

Symplectic Duality of $T^*Gr(k,n)$

Hunter Dinkins

摘要:

在本文中,我们探讨了辛对偶(也称为三维镜像对称)在枚举几何的设置的一个后果。准映射理论允许人们将称为顶点函数的超几何函数与顶点簇联系起来。本文证明了$T^*Gr(k,n)$及其辛对偶的顶点函数之间的关系式。在证明过程中,我们研究了对角作用于Macdonald多项式的一类$q$ -差分算子。我们的结果可以从组合的角度解释为提供一个评估公式的$q$ -Selberg型积分。

英文摘要:

In this paper, we explore a consequence of symplectic duality (also known as 3d mirror symmetry) in the setting of enumerative geometry. The theory of quasimaps allows one to associate hypergeometric functions called vertex functions to quiver varieties. In this paper, we prove a formula which relates the vertex functions of $T^*Gr(k,n)$ and its symplectic dual. In the course of the proof, we study a family of $q$-difference operators which act diagonally on Macdonald polynomials. Our results may be interpreted from a combinatorial perspective as providing an evaluation formula for a $q$-Selberg type integral.
