Modules with 1-dimensional socle and components of Lusztig quiver varieties in type A
arXiv:1009.0272
Abstract
We study modules with 1-dimensional socle for preprojective algebras for type A quivers. In particular, we classify such modules, determine all homomorphisms between them, and then explain how they may be used to describe the components of Lusztig quiver varieties.
