Reverse mathematics of rings [PDF]
, 2021 <p>Using the tools of reverse mathematics in second-order arithmetic, as developed by Friedman, Simpson, and others, we determine the axioms necessary to develop various topics in commutative ring theory. Our main contributions to the field are as follows.

On $\mathcal Z$-reflexive rings [PDF]
Mathematica BohemicaWe introduce the notion of $\mathcal Z$-reflexive rings to describe reflexivity of rings in terms of their singular ideals. We show that $\mathcal Z$-reflexive ring is proper common generalization of a central reflexive ring, $\mathcal Z$-reversible ring,

Recent Progress in Porous Fused Aromatic Networks and Their Applications
Small Science, 2021 Porous materials are ubiquitous in nature and play central roles in ecosystems and human life. Porous fused aromatic networks (P‐FANs) are emerging as a new class of porous organic materials, which can be precisely constructed from organic precursors via

, 2006 In this book we define the new notion of neutrosophic rings. The motivation for this study is two-fold. Firstly, the classes of neutrosophic rings defined in this book are generalization of the two well-known classes of rings: group rings and semigroup ...

A generalization of reflexive rings [PDF]
Mathematica BohemicaWe introduce a class of rings which is a generalization of reflexive rings and $J$-reversible rings. Let $R$ be a ring with identity and $J(R)$ denote the Jacobson radical of $R$.

Directed zero-divisor graph and skew power series rings [PDF]
Transactions on Combinatorics, 2018 Let $R$ be an associative ring with identity and $Z^{\ast}(R)$ be its set of non-zero zero-divisors. Zero-divisor graphs of rings are well represented in the literature of commutative and non-commutative rings. The directed zero-divisor graph of $R$

On a Generalized Semicommutative Ring
Tikrit Journal of Pure Science, 2019 Let R be a ring with identity. In this paper, we introduce some new results in a class of rings which refers to generalization of semicommutative rings called Q-semicommutative rings whenever x2=0 implies xRx=0, for any a ∈R [7]. They study investigates
