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, $\Gamma$-integral, principal $A$-determinant.
