Deformations of formal embeddings of schemes

Abstract: ABSTRACT. A family of isolated singularities of k-varieties will be here called equisingular if it can be simultaneously resolved to a family of hypersurfaces embedded in nonsingular spaces which induce only locally trivial deformations of pairs of schemes over local artin Ac-algebras. The functor of locally trivial deformations of the formal embedding of an exceptional set has a versal object in the sense of Schlessinger. When the exceptional set Xq is a collection of nonsingular curves meeting normally in a … Show more
