Frobenius map and the $p$-adic Gamma function

Number Theory 2010-06-03 v1

Abstract

In this note we study the relationship between the power series expansion of the Dwork exponential and the Mahler expansion of the pp-adic Gamma function. We exploit this relationship to prove that certain quantities that appeared in our previous computations of the Frobenius map can be expressed in terms of the derivatives of the pp-adic Gamma function at 0. This is used to prove a conjecture about the non-trivial off-diagonal entry in the Frobenius matrix of the mirror quintic threefold.
