Simple-minded systems and coherent rings [PDF]

arXiv
Let $A$ be a finite dimensional algebra over an algebraically closed field. We present a relationship between simple-minded systems and coherent rings.

On Central Skew Armendariz rings [PDF]

arXiv, 2014
For a ring endomirphism, we introduce the central skew Armendariz rings, which are a generalization of skew Armendariz rings and central Armendariz rings, and investigate their properties.

Aspects on weak, s-CS and almost injective rings [PDF]

arXiv, 2015
It is not known whether right CF-rings (FGF-rings) are right artinian (quasi-Frobenius). This paper gives a positive answer of this question in the case of weak CS (s-CS) and GC2 rings. Also we get some new results on almost injective rings.

On primitive ideals in polynomial rings over nil rings [PDF]

arXiv, 2004
Let R be a nil ring. We prove that primitive ideals in the polynomial ring R[x] in one indeterminate over R are of the form I[x] for some ideals I of R.

arXiv, 2010
In this paper I consider the structure of the polylinear mapping of the free algebra over the commutative ring.

On Centrally Essential Rings [PDF]

arXiv
A ring $R$ with center $C$ is said to be centrally essential if the module $R_C$ is an essential extension of the module $C_C$. In this paper, we study properties of ideals of centrally essential rings, centrally essential quaternion algebras, and group rings of Hamiltonian groups.
