On Pellarin's $L$-series

Abstract

Necessary and sufficient conditions are given for a negative integer to be a trivial zero of a new type of LL-series recently discovered by F. Pellarin, and it is shown that any such trivial zero is simple. We determine the exact degree of the special polynomials associated to Pellarin's LL-series. The theory of Carlitz polynomial approximations is developed further for both additive and Fq\mathbb{F}_q-linear functions. Using Carlitz' theory we give generating series for the power sums occurring as the coefficients of the special polynomials associated to Pellarin's series, and a connection is made between the Wagner representation for χt\chi_t and the value of Pellarin's LL-series at 1.
