A comparison of the Carlitz and digit derivatives bases in function field arithmetic

Number Theory 2007-05-23 v1

Abstract

In this paper we compare several properties and constructions of the Carlitz polynomials and digit derivatives for continuous functions on \Fq[[T]].\F_q[[T]]. In particular, we show a close relation between them as orthonormal bases. Moreover, parallel to Carlitz's coefficient formula, we give the closed formula for the expansion coefficients in terms of the digit derivatives.
