Abstract:
We prove two theorems on the domains of convergence for A-hypergeometric series and for associated Mellin–Barnes type integrals. The exact convergence domains are described in terms of amoebas and coamoebas of the corresponding principal A-determinants.
Keywords:A-hypergeometric series, Mellin–Barnes integral, Γ-integral, principal A-determinant.
