Abstract

In this article, we introduce the concept of weakly II-clean ring, for any ideal II of a ring RR. We show that, for an ideal II of a ring RR, RR is uniquely weakly II-clean if and only if R/IR/I is semi boolean and idempotents can be lifted uniquely weakly modulo II if and only if for each aRa\in R, there exists a central idempotent eRe\in R such that either aeIa-e\in I or a+eIa+e\in I and II is idempotent free. As a corollary, we characterize weakly JJ-clean ring. Also we study various properties of weakly II-clean ring.
