Gevrey solutions of the irregular hypergeometric system associated with an affine monomial curve
María‐Cruz Fernández‐Fernández, Francisco Jesús Castro Jiménez · Transactions of the American Mathematical Society · 2010
We describe the Gevrey series solutions at singular points of the irregular hypergeometric system (GKZ system) associated with an affine monomial curve. We also describe the irregularity complex of such a system with respect to its singular support.
