Perverse sheaves and quivers

WebSince its inception around 1980, the theory of perverse sheaves has been a vital tool of fundamental importance in geometric representation theory. This book, which aims to make this theory accessible to students and researchers, is divided into two parts. The first six chapters give a comprehensive account of constructible and perverse sheaves ... WebAbstractIn this article we consider the general definition of Lusztig sheaves for arbitrary quivers, possibly carrying loops. We prove a conjecture raised by Lusztig asking if the more elementary Lusztig perverse sheaves are enough to span the whole Grothendieck group usually built with these sheaves.
