%0 Journal Article %T On regularity in codimension one of irreducible components of module varieties %A Grzegorz Bobinski %J Mathematics %D 2008 %I arXiv %X Let A be a tame quasi-tilted algebra and d the dimension vector of an indecomposable A-module. In the paper we prove that each irreducible component of the variety of A-modules of dimension vector d is regular in codimension one. %U http://arxiv.org/abs/0804.2085v1
