AI总结:

本文构造了一类含m个变量、p+(p-1)m个参数的超几何级数及其微分方程组,统一了广义超几何级数和Lauricella F_C函数,并证明其秩为p^m、给出积分表示与奇异轨迹。

摘要:

我们定义了一个含有m个变量、具有p+(p-1)m个参数的超级几何级数,当m=1时它退化为广义超几何级数_pF_{p-1},当p=2时退化为Lauricella的m变量超几何级数F_C。我们给出了一个消灭该级数的超几何微分方程组。在参数满足某些非整数条件下,我们给出了该级数的欧拉型积分表示,以及该方程组在原点附近一点的p^m个线性无关解。我们证明该方程组的秩为p^m,并确定了其奇异轨迹。

英文摘要:

We define a hypergeometric series in $m$ variables with $p+(p-1)m$ parameters, which reduces to the generalized hypergeometric series $_pF_{p-1}$ when $m=1$, and to Lauricella's hypergeometric series $F_C$ in $m$ variables when $p=2$. We give a system of hypergeometric differential equations annihilating the series. Under some non-integral conditions on parameters, we give an Euler type integral representation of the series, and linearly independent $p^m$ solutions to this system around a point near to the origin. We show that this system is of rank $p^m$, and determine its singular locus.
