Some new characterizations of periodic rings
J Cui, P Danchev - Journal of Algebra and Its Applications, 2020 - World Scientific
A ring R is called periodic if, for every a in R, there exist two distinct positive integers m and n
such that am= an. The paper is devoted to a comprehensive study of the periodicity of …

On UJ-rings
UJ-rings are studied, ie ring in which all units can be presented in a form 1+ x, for some x\in
J (R). The behavior of UJ-rings under various algebraic construction is investigated. In …

Rings close to periodic with applications to matrix, endomorphism and group rings
We examine those matrix rings whose entries lie in periodic rings equipped with some
additional properties. Specifically, we prove that the famous Diesl's question whether or not …

A classification of ring elements in skew PBW extensions over compatible rings
For a skew PBW extension over a right duo compatible ring, we characterize several kinds of
their elements such as units, idempotent, von Neumann regular, $\pi $-regular and the clean …

Rings whose elements are sums of m-potents and nilpotents
For a fixed natural number m≥ 2, an element a of a ring R is m-nil clean if a= e+ b where
em= e∈ R and b is nilpotent; if further eb= be, a is called strongly m-nil clean. The ring R is …
em= e∈ R and b is nilpotent; if further eb= be, a is called strongly m-nil clean. The ring R is …
Conjugate (nil) clean rings and Köthe's problem
J Matczuk - Journal of Algebra and Its Applications, 2017 - World Scientific
Question 3 of [3] asks whether the matrix ring M n (R) is nil clean, for any nil clean ring R. It is
shown that, positive answer to this question is equivalent to positive solution for Köthe's …

A Note on Weakly Nil-Clean Rings
R Barati, A Moussavi - Mediterranean Journal of Mathematics, 2023 - Springer
A ring R is (strongly) weakly nil clean if every element in R is the sum or difference of a
nilpotent and an idempotent (that commutes). In this note, we show that if R is strongly nil …
