An elliptic generalization of multiple polylogarithms
We introduce a class of functions which constitutes an obvious elliptic generalization of multiple polylogarithms. A subset of these functions appears naturally in the ϵ-expansion of the imaginary part of the two-loop massive sunrise graph. Building upon the well known properties of multiple polylo...
