DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BRAG/6/">The
  geography of moduli spaces of torsion free sheaves</a>\nby Charles Almeid
 a (Federal University of Minas Gerais (UFMG)) as part of Brazilian algebra
 ic geometry seminar\n\n\nAbstract\nIn this talk I will describe new irredu
 cible components of the moduli space of rank 2 semistable torsion free she
 aves on the 3-dimensional projective space\, whose generic point correspon
 ds to non-locally free sheaves. As an application\, I will compute the num
 ber of irreducible components of the moduli space of torsion free sheaves\
 , with first\, second and third Chern classes equal to -1\, 2 and 2 respec
 tively. Additionaly\, I will give an idea of how to prove that this moduli
  space is connected. This is a joint work with Marcos Jardim and Alexander
  S. Tikhomirov.\n
