设X/Fq是定义在特征为p的有限域上的光滑仿射几何连通曲线,本文研究了~ h(X)的p-adic特征标上的L-函数的解析性质和算术性质。所谓p-adic特征标,是指连续同态p:7 rl(X)--* Ax,其中A是具有混合特征p的完备局部Noether环,其极大理想m和有限剩余域k= A/m.与p相对应的是X上A-模N的一个6层,且上同调群H~.(十)|Fq,N)是已知的J?参见A-模(下面的引理(2.1))。因此,有必要定义
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
