A note on deformations of regular embeddings

arXiv:1701.08171 · doi:10.1007/s12215-016-0276-4

Abstract

In this paper we give a description of the first order deformation space of a regular embedding of reduced algebraic schemes. We compare our result with results of Ran (in particular [Ran, Prop. 1.3]).
