关于$q$ -同构单值形变和$q$ -Nekrasov函数

On $q$-Isomonodromic Deformations and $q$-Nekrasov Functions

Hajime Nagoya

摘要:

我们用$q=t$构造了一个关于5维Nekrasov函数的秩$N$的$q$ -差Lax对的基本系统.我们的基本系统退化的极限$q\to 1$的基本系统的微分Lax对,这产生的Fuji-Suzuki-Tsuda系统。我们引入我们系统的τ函数作为5维Nekrasov函数的傅里叶变换。利用基本系统在$0$和$\infty$上的渐近展开,得到了τ函数的几个行列式恒等式.

英文摘要:

We construct a fundamental system of a $q$-difference Lax pair of rank $N$ in terms of 5d Nekrasov functions with $q=t$. Our fundamental system degenerates by the limit $q\to 1$ to a fundamental system of a differential Lax pair, which yields the Fuji-Suzuki-Tsuda system. We introduce tau functions of our system as Fourier transforms of 5d Nekrasov functions. Using asymptotic expansions of the fundamental system at $0$ and $\infty$, we obtain several determinantal identities of the tau functions.
