Irreducible components of quiver Grassmannians (1303.4585v3)
Published 19 Mar 2013 in math.RT and math.AG
Abstract: We prove a decomposition theorem for irreducible components of Grassmannians of submodules, as well as for other schemes arising from representation theory, thus generalising the result of Crawley-Boevey and Schroer for module varieties. The method is based on jet space calculations, using that the formation of direct sums induces a separable morphism of schemes.
