Monodromy and Isomonodromy for Linear -Difference Systems with Coefficient Matrix
Jinghong Lin, Qian Tang, Xiaomeng Xu
In this paper, we construct canonical fundamental solutions for linear -difference systems with coefficient matrix , develop the associated isomonodromy theory, and study…

Stokes Phenomenon and Yangians
Qian Tang, Xiaomeng Xu
In this paper, we first establish a connection between Yangians and the unique formal solution of the quantum hypergeometric differential equations at irregular singularities. We t…

The Boundary Condition for Some Isomonodromy Equations
Qian Tang, Xiaomeng Xu
In this article, we study a special class of Jimbo-Miwa-Mori-Sato isomonodromy equations, which can be seen as a higher-dimensional generalization of Painlevé VI. We first construc…
