On the relative zeta function in function fields

Daisuke Shiomi

Nagoya University

Abstract

In the previous paper [8], the author gave a determinant formula of relative zeta function for cyclotomic function fields. Our purpose of this paper is to extend this result for more general function fields. As an application of our formula, we will give determinant formulas of class numbers for constant field extensions.

Keywords: zeta functions, class numbers, function fields
