On generalized deformation problems
Abstract
Let be a Noetherian local ring and an ideal with finite projective dimension. If satisfies some property , it is natural to ask whether would also satisfy this property . This is called the generalized deformation problem. In this paper we discuss some properties that would satisfy this problem. There are two main parts for this paper. In the first part we focus on F-singularities of characteristic . We show that F-injective satisfies this problem for the Cohen-Macaulay ring case and F-rational satisfies this problem for the excellent ring case. In the second part there is no restriction on the characteristic of , we show that when is catenary and equidimensional with perfect, then the Serre's Condition would satisfy the problem. And the Serre's Condition , , normal rings, reduced rings and domains would always satisfy this problem.

We have fixed an error in the proof of the previous Proposotion 3.8 and Proposotion 3.9 by adding CM condition. The main results remain unchanged
