Abstract

As is well known, idempotents in any ring R lift modulo any nil idea I. That is, if a ϵ R and (a 2 -a) ϵ I there is an i ϵ I with (a + i) 2 -- (a + i) = 0. An idempotent is a zero of the polynomial x 2 −x 2 , and a nil element satisfies x n for some n. Seen this way, lifting occurs in considerable generality We assume R has a unit, and handle the non-unital case at the end of this paper.
