A Note On the moduli space of rank two vector bundles on Hirzebruch surfaces
L. Roa-Leguizamón
The aim of this paper is to study the Segre invariant for rank vector bundles on Hirzebruch surfaces , . We give necessary conditions in order to determ…
Stability conditions for coherent systems on Integral Curves
Marcos Jardim, Leonardo Roa-Leguizamón, Renato Vidal Martins
We present stability conditions for the category of coherent systems on an integral curve. We define a three-parameter family of pre-stability conditions in its derived category us…
Clifford's Theorem for Coherent Systems on surfaces
L. Costa, I. Macías Tarrío, L. Roa-Leguizamón
Let X be a smooth irreducible projective surface. The aim of this paper is to establish a version of Clifford's theorem for coherent systems on X.
On the Hilbert scheme of the moduli space of torsion free sheaves on surfaces
O. Mata-Gutiérrez, L. Roa-Leguizamón, H. Torres-López
The aim of this paper is to determine a bound of the dimension of an irreducible component of the Hilbert scheme of the moduli space of torsion-free sheaves on surfaces. Let be…
