Mellin Transform formulas for special values of Goss $L$-functions

Abstract

In the present paper, we provide formulas for the special values of dual Goss $L$-functions of Drinfeld modules at any non-negative integer in terms of the determinant of the values of a motivic map, extensively studied by both authors in 2026, for a large class of Anderson modules. Our result may be seen as a function field analogue of conjectural formulas for special values of motivic $L$-functions in terms of algebraic Mellin integrals.
