The algebraic de Rham realization of the elliptic polylogarithm via the Poincaré bundle

Abstract

We describe the algebraic de Rham realization of the elliptic polylogarithm for arbitrary families of elliptic curves in terms of the Poincare bundle. Our work builds on previous work of Scheider and generalizes results of Bannai, Kobayashi and Tsuji, and Scheider. As an application, we compute the de Rham-Eisenstein classes explicitly in terms of certain algebraic Eisenstein series.
