Gevrey solutions of irregular hypergeometric systems in two variables
arXiv:0811.3390
Abstract
We describe the Gevrey series solutions at singular points of the irregular hypergeometric system (GKZ system) associated with an affine plane monomial curve. We also describe the irregularity complex of such a system with respect to its singular support.
