DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TRAC/15/">Fr
 amed quiver moduli spaces</a>\nby Markus Reineke as part of The TRAC Semin
 ar - Théorie de Représentations et ses Applications et Connections\n\n\n
 Abstract\nThe aim of this talk is to review the utility of studying framed
  versions of moduli spaces of quiver representations. We first review the 
 general construction of framed moduli spaces\, and discuss several classes
  of examples (for example\, acyclic quivers and quiver Grassmannians\, m-l
 oop quivers and explicit normal forms). Turning to the topology of framed 
 quiver moduli spaces\, we state a formula for their Betti numbers\, and ex
 hibit a coupled system of functional equations relating Euler characterist
 ic of framed and unframed moduli spaces. Finally\, we study the geometry o
 f the Hilbert-Chow map from framed to unframed moduli spaces\, and derive 
 a formula for the intersection Betti numbers of unframed moduli spaces fro
 m this.\n
