Mellin Transform Formulas for Anderson Modules and Hints of Modularity

Abstract

In the present paper, we introduce formulas for the logarithm function of abelian, uniformizable Anderson modules. Combining our formulas with a motivic map introduced recently by the second author, we relate special values of dual Goss $L$-functions of Drinfeld modules to the rigid analytic trivialization of their corresponding $t$-comotives. We apply these formulas to relate certain $L$-values to special values of matrix valued modular forms, generalizing the vector valued Drinfeld modular forms of Pellarin and Pellarin and Perkins in the rank two setting.
