Journal ArticleDOI
Nil clean rings
TL;DR: In this paper, a general theory based on idempotents and direct sum decompositions was developed to unify several variations of the notions of clean and strongly clean, and a new class of clean rings was investigated.
Journal ArticleDOI
Idempotent lifting and ring extensions
TL;DR: The lifting of idempotents is not a Morita invariant as discussed by the authors, and it can be seen as a special case of a more general theorem about completions, which states that conjugate idempots are not necessarily related by a string of perspectivities.
Journal ArticleDOI
Strongly clean matrices over arbitrary rings
TL;DR: In this article, the companion matrix of a monic polynomial over an arbitrary ring R is characterized in terms of a type of ideal-theoretic factorization, called an iSRC factorization.
Journal ArticleDOI
A note on completeness and strongly clean rings
TL;DR: In this article, the authors investigated the behavior of strong cleanness under certain ring extensions and showed that if R is a ring which is complete with respect to an ideal I and if x is an element of R whose image in R / I is strongly π -regular, then x is strongly clean in R.
Journal ArticleDOI
Classifying annihilating-ideal graphs of commutative artinian rings
TL;DR: In this article, the annihilating ideal graph of a commutative ring was investigated and the main goal was to determine which algebraic properties of a ring are not annihilated.
