Rings such that, for each unit , belongs to the
Peter Danchev, Arash Javan, Omid Hasanzadeh +2
We study in-depth those rings for which, there exists a fixed , such that lies in the subring of for every unit . We succeeded to describe…
Rings Whose Non-Invertible Elements are Weakly Nil-Clean
Peter Danchev, Arash Javan, Omid Hasanzadeh +1
In regard to our recent studies of rings with (strongly, weakly) nil-clean-like properties, we explore in-depth both the structural and characterization properties of those rings w…
Rings Whose Non-Invertible Elements Are Nil-Clean
Peter Danchev, Arash Javan, Omid Hasanzadeh +1
We systematically study those rings whose non-units are a sum of an idempotent and a nilpotent. Some crucial characteristic properties are completely described as well as some stru…
On Some Extensions of -Regular Rings
Peter Danchev, Arash Javan, Ahmad Moussavi
Some variations of -regular and nil clean rings were recently introduced in \cite{5,8,7}, respectively. In this paper, we examine the structure and relationships between these…
Rings whose Non-Invertible Elements are Strongly Nil-Clean
Peter Danchev, Omid Hasanzadeh, Arash Javan +1
We consider in-depth and characterize in certain aspects those rings whose non-units are strongly nil-clean in the sense that they are a sum of commuting nilpotent and idempotent.…
Rings with Quasinilpotent for Each Unit
Peter Danchev, Arash Javan, Omid Hasanzadeh +1
We define and explore in-depth the notion of {\it UQ rings} by showing their important properties and by comparing their behavior with that of the well-known classes of UU rings an…
