The moduli space of torsion-free sheaves with quasi-maximal third Chern class

Charles Almeida, Marcos Jardim, Leonardo Oliveira

In this paper, we investigate the geometry of the Gieseker moduli space of semistable rank $2$ torsion-free sheaves on ${\mathbb{P}}^3$ with Chern classes $(c_1, c_2, c_3) = (-1, c_2…
