Desingularizations of quiver Grassmannians via graded quiver varieties (1305.7502v1)
Published 31 May 2013 in math.AG and math.RT
Abstract: Inspired by recent work of Cerulli-Feigin-Reineke on desingularizations of quiver Grassmannians of representations of Dynkin quivers, we obtain desingularizations in considerably more general situations and in particular for Grassmannians of modules over iterated tilted algebras of Dynkin type. Our desingularization map is constructed from Nakajima's desingularization map for graded quiver varieties.
