本文描述了一类超几何系统级数解的参数行为。更确切地说,我们构造显式分层的参数空间,使得在每一层上,系统的级数解是全纯的。引用
We describe the parametric behavior of the series solutions of an-hypergeometric system. More precisely, we construct explicit stratifications of the parameter space such that, on each stratum, the series solutions of the system are holomorphic. References
