Multiple sine, multiple elliptic gamma functions and rational cones

Abstract

We define generalizations of the multiple elliptic gamma functions and the multiple sine functions, labelled by rational cones in ${\mathbb{R}}^r$. For $r=2,3$ we prove that the generalized multiple elliptic gamma functions enjoy a modular property determined by the cone. This generalizes the modular properties of the elliptic gamma function studied by Felder and Varchenko. The generalized multiple sine enjoy a related infinite product representation, generalizing the results of Narukawa for the ordinary multiple sine functions.
