Coherent Sheaves on Ribbons and their Moduli

By Michele Savarese
A ribbon is a non-reduced curve modelled on the first infinitesimal neighbourhood of a smooth curve in a surface. This paper is devoted to describe some properties of coherent sheaves on such a curve and their Simpson moduli space. In particular we give necessary and sufficent conditions for the existence...
