Spin curves over non-stable curves

Algebraic Geometry 2007-06-13 v2

Abstract

Here we consider degenerations of stable spin curves for a fixed smoothing of a non-stable curve: we are able to give enumerative results and a description of limits of stable spin curves. We give a geometrically meaningful definition of spin curves over non-stable curves.
