Desingularizations of quiver Grassmannians via graded quiver varieties
Bernhard Keller, Sarah Scherotzke
Inspired by recent work of Cerulli-Feigin-Reineke on desingularizations of quiver Grassmannians of representations of Dynkin quivers, we obtain desingularizations in considerably m…

Graded quiver varieties and derived categories
Bernhard Keller, Sarah Scherotzke
Inspired by recent work of Hernandez-Leclerc and Leclerc-Plamondon we investigate the link between Nakajima's graded affine quiver varieties associated with an acyclic connected qu…
