摘要翻译：
本文介绍了有理D-连接的tau-函数及其同模变换。证明了在连续极限下我们的tau函数与Jimbo-Miwa-Ueno tau函数一致，计算了导致差分Painleve V和差分Painleve VI方程的等价变换的tau函数，并证明了一类离散随机矩阵型模型的间隙概率可以看作是相关D-连接的tau函数。

英文摘要：
We introduce the tau-function of a rational d-connection and its isomonodromy transformations. We show that in a continuous limit our tau-function agrees with the Jimbo-Miwa-Ueno tau-function, compute the tau-function for the isomonodromy transformations leading to difference Painleve V and difference Painleve VI equations, and prove that the gap probability for a wide class of discrete random matrix type models can be viewed as the tau-function for an associated d-connection.
