Let X/Fq be a smooth affine geometrically connected curve defined over a finite field of characteristic p. In this paper we will study the analytic and arithmetic properties of the L-functions attached to p-adic characters of~ h (X). By a p-adic character, we mean a continuous homomorphism p: 7rl (X)--* A x where A is a complete local noetherian ring of mixed characteristic p with maximal ideal m and finite residue field k= A/m. Corresponding to p is an 6tale sheaf of A-modules N on X, and the cohomology group H~.(X| Fq, N) is known to be a J? ee A-module (Lemma (2.1) below). It therefore makes sense to define
