Title: Confluent A-hypergeometric functions and rapid decay homology cycles

Abstract:
In 1990, Gelfand, Kapranov and Zelevinsky proved that their
A-hypergeometric functions admit integral representations. In this
talk,we introduce a generalization of this result to Adolphson's
confluent A-hypergeometric functions. Hien's rapid decay homology cycles
will be used to prove our main theorem.Moreover we obtain a formula
for the asymptotic expansions at infinity of confluent
$A$-hypergeometric functions.This is a joint work with
A. Esterov(arXiv:1107.0402v2 [math.AG]).
