On Koszul complex of a supermodule
Darío Sánchez Gómez, Fernando Sancho de Salas
This paper is devoted to an exposition of the Koszul complex of a supermodule and its Berezinian from an intrinsic and as general as possible point of view. As an application, an a…
Moduli Spaces of Semistable Sheaves on Singular Genus One Curves
Daniel Hernández Ruipérez, Ana Cristina López Martín, Darío Sánchez Gómez +1
We find some equivalences of the derived category of coherent sheaves on a Gorenstein genus one curve that preserve the (semi)-stability of pure dimensional sheaves. Using them we…
A Characterization of Jacobians by the Existence of Picard Bundles
Ana Cristina López Martín, Ernesto Carlo Mistretta, Darío Sánchez Gómez
Based on the Matsusaka-Ran criterion we give a criterion to characterize when a principal polarized abelian variety is a Jacobian by the existence of Picard bundles.
