-Fine Rings

Peter Danchev, Omid Hasanzadeh, Ahmad Moussavi +1

We introduce and study the so-termed {\it -fine rings}, a new class of rings that generalizes the classical {\it fine rings} introduced by Călugăreanu-Lam in J. Algebra \&…

Expanding Generalized Fine Rings

Ahmad Moussavi, Peter Danchev, Arash Javan +1

We introduce and study the so-called {\it generalized -fine rings}, where every element outside the Jacobson radical is the sum of a unit and an element from the set $\sq…

A Generalization of UQ Rings

Peter Danchev, Mina Doostalizadeh, Omid Hasanzadeh

We examine the newly defined class of {\it - rings} described by the condition that for every unit , where denotes the set of quasi-n…

Rings with Clean-Like Properties: Endomorphism, Matrix and Structural Theorems

Adel N. Abyzov, Andrey R. Chekhlov, Peter V. Danchev +1

We investigate three clean-like properties for arbitrary rings, for endomorphism rings of abelian groups and for matrix rings over finite fields. Specifically, we study and establi…

A Generalization of U Rings

Peter Danchev, Omid Hasanzadeh, Ahmad Moussavi +1

In this paper, we introduce and study a new class of rings calling them {\it weakly -rings}, hereafter abbreviated as {\it -rings} for short. A ring is said to be $WΔU…

Hereditarily and Super Bassian Modules over Certain Rings

Peter Vassilev Danchev, Truong Cong Quynh, Jan Žemlička

We characterize in certain basic cases when a module over a ring is either {\it hereditarily Bassian} or {\it super Bassian} in the sense that either each its proper submodule is B…

Weakly Rings

Zari Vesali Mahmood, Ahmad Moussavi, Peter Danchev

We introduce and study the so-called {\it weakly rings} (hereafter abbreviated as {\it rings} for short), in which every unit is of the form or …

Rings whose Non-Units are a Unit Multiple of an Element from

Omid Hasanzadeh, Ahmad Moussavi, Peter Danchev

This paper introduces and studies a new class of rings called {\it -rings}. A ring is if every non-unit element can be written as the product of a unit and a…

Rings Such That Lies In For Each Unit

Peter Danchev, Mina Doostalizadeh, Mehrdad Esfandiar +1

We investigate the so-called {\it rings}, a new type of rings in which every unit can be written as with . These rings were defined and studied by S…

Unit Uniquely Clean Rings

Mina Doostalizadeh, Ahmad Moussavi, Peter Danchev

We define the class of {\it unit uniquely clean} rings ({\it UnitUC} for short), that is a common generalization of uniquely clean rings and strongly nil clean rings. Abelian {\it…

Rings Whose Units Have Identity Plus Quasi-Nilpotent Square

Shahram Najafi, Ahmad Moussavi, Peter Danchev

In this paper, we investigate the structural and characterizing properties of the so-called {\it 2-UQ rings}, that are rings such that the square of every unit is the sum of an ide…

Weakly Strongly 2-Nil-Clean Rings

Peter Danchev, Mina Doostalizadeh, Ahmad Moussavi

In this paper, we introduce and explore in-depth the notion of {\it weakly strongly 2-nil-clean rings} as a common non-trivial generalization of both strongly 2-nil-clean rings and…

On Strongly \( J^{\#} \)-Clean Rings

Peter Danchev, Gholamreza Karamali, Omid Hasanzadeh +1

We define and examine the class of {\it strongly \( J^{\#} \)-clean rings} consisting of those rings such that each element of is the sum of an idempotent from and an e…

On Rings with the 2-UNJ Property

Zari Vesali Mahmood, Ahmad Moussavi, Peter Danchev

In this paper, we introduce a new class of rings calling them {\it 2-UNJ rings}, which generalize the well-known 2-UJ, 2-UU and UNJ rings. Specifically, a ring is called 2-UNJ…

Rings Whose Non-Units are Square-Nil Clean

Mina Doostalizadeh, Ahmad Moussavi, Peter Danchev

We consider in-depth and characterize in certain aspects the class of so-called {\it strongly NUS-nil clean rings}, that are those rings whose non-units are {\it square nil-clean}…

Some Results on Triangular Coefficient Matrix Rings

Peter Danchev, Gholamreza Karamali, Hessam Hosseinnezhad +1

In this paper, we introduce the concept of a {\it triangular coefficient matrix ring} and investigate the structure of its ideals. We then characterize the radicals of the ring \(…

Jordan Derivation On Generalized Triangular Matrix Rings

Peter Danchev, Ayda Fatehi, Masoome Zahiri +1

In this note, we prove that any Jordan derivation on the generalized matrix ring is a derivation. This extends some well-known results of this branch due to Brešar et al…

Matrices over finite fields of odd characteristic as sums of diagonalizable and square-zero matrices

Peter Danchev, Esther García, Miguel Gómez Lozano

Let be a finite field of odd characteristic. When , we prove that every matrix admits a decomposition into where is diagonalizable and…

Rings for Which f.g. Projective Modules Have the FI-extending Property

Peter Danchev, M. Zahiri, S. Zahiri

A right -module is said to be {\it FI-extending} if any fully invariant submodule of is essential in a direct summand of . In this short note we prove that if has…
