Local Zeta Functions Supported on Analytic Submanifolds and Newton Polyhedra

Abstract

The local zeta functions (also called Igusa's zeta functions) over p-adic fields are connected with the number of solutions of congruences and exponential sums mod pm. These zeta functions are defined as integrals over open and compact subsets with respect to the Haar measure. In this article, we introduce new integrals defined over submanifolds, or more generally, over nondegenerate complete intersection varieties, and study their connections with some arithmetical problems such as estimation of exponential sums mod pm. In particular, we extend Igusa's method for estimating exponential sums mod pm to the case of exponential sums mod pm along nondegenerate smooth varieties.
