Moduli of sheaves on ribbons
Michele Savarese, Filippo Viviani
We study the geometry of the moduli stack of torsion-free sheaves on ribbons. We introduce a stratification of the stack by the complete type of the sheaves, and we investigate the…
Generalized line bundles on primitive multiple curves and their moduli
Michele Savarese
In this paper, we study generalized line bundles over , a primitive multiple curve of arbitrary multiplicity , where is a positive integer. In particular, we give a str…
Coherent Sheaves on Ribbons and their Moduli
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 shea…
On the irreducible components of the compactified Jacobian of a ribbon
Michele Savarese
In this paper we study the irreducible components of the compactified Jacobian of a ribbon of arithmetic genus over a smooth curve of genus . We…
