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

Yoshiaki Goto, Keiji Matsumoto

We consider the system $F_{4} (a, b, c)$ of differential equations annihilating Appell's hypergeometric series $F_{4} (a, b, c; x)$ . We find the integral representations for four li…
