Singular elliptic genus of normal surfaces

Algebraic Geometry 2007-11-29 v1

Abstract

We define the singular elliptic genus for arbitrary normal surfaces, prove that it is a birational invariant, and show that it generalizes the singular elliptic genus of Borisov and Libgober and the stringy χy\chi_y genus of Batyrev and Veys.
