Exponential sums and finite field $A$-hypergeometric functions

Number Theory 2012-10-25 v1

Abstract

We define finite field AA-hypergeometric functions and show that they are Fourier expansions of families of exponential sums on the torus. For an appropriate choice of AA, our finite field AA-hypergeometric function can be specialized to the finite field kFk1{}_kF_{k-1}-hypergeometric function defined by McCarthy.
