Appell超几何函数F_4的单值表示与扭周期关系

The monodromy representation and twisted period relations for Appell's hypergeometric function F_4

Yoshiaki Goto, Keiji Matsumoto

摘要:

考虑微分方程组$\mathcal{F}_4(a,b,c)$零化Appell超几何级数$F_4(a,b,c;x)$ .我们找到了由超几何级数$F_4$表示的四个线性无关解的整表示。利用扭(余)同调群的交形式,给出了$\mathcal{F}_4(a,b,c)$的单值表示和$\mathcal{F}_4$基本解系的扭周期关系.

英文摘要:

We consider the system $\mathcal{F}_4(a,b,c)$ of differential equations annihilating Appell's hypergeometric series $F_4(a,b,c;x)$. We find the integral representations for four linearly independent solutions expressed by the hypergeometric series $F_4$. By using the intersection forms of twisted (co)homology groups associated with them, we provide the monodromy representation of $\mathcal{F}_4(a,b,c)$ and the twisted period relations for the fundamental systems of solutions of $\mathcal{F}_4$.
