Monodromy of A-hypergeometric functions
  Using Mellin-Barnes integrals we give a method to compute a relevant subgroup of the monodromy group of an A-hypergeometric system of differential equations. Presumably this group is the full monodromy group of the system.   This article is a major rewrite of an article posted 2 years ago.
