DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UFPB/25/">Mo
 duli of flags of sheaves: a quiver description</a>\nby Valeriano Lanza (UF
 F) as part of Seminários de Matemática da UFPB\n\n\nAbstract\nIn [1]\, t
 he moduli spaces of framed flags of sheaves on P2 were described by means 
 of representations of the so-called enhanced ADHM quiver. We first review 
 those results\, with a recent refinement concerning the chamber structure 
 in the space of stability parameters. We shall then discuss the obstructio
 n theory for these moduli spaces\, showing in general that they have a  pe
 rfect obstruction theory\, and providing for specific choices of invariant
 s a class of unobstructed points. Finally\, open problems and possible fur
 ther developments will be presented. This is a joint work with Rodrigo von
  Flach and Marcos Jardim.\n\n[1] R. A. von Flach and M. Jardim\, Moduli sp
