Noncommutativity and Noncentral Zero Divisors

چکیده
Let R be a ring, Z its center, and D the set of zero divisors. For finite noncommutative rings, it is known that D\Z = ∅. We investigate the size of |D\Z| in this case and, also, in the case of infinite noncommutative rings with D\Z = ∅.

Elements of Hypercomputation on R and Z2 with the Dickson-Albert inductive process
This report is a follow-up for [3, 4, 5, 6, 14, 15]. It reviews the properties of the real and binary algebras of numbers generated by the Dickson-Albert inductive process. Properties with regard to commutativity, associativity, alternativity and zero divisors on R and Z2 are contrasted. It is shown how noncommutativity, non alternativity and zero divisors for higher dimensional hypercomplex al...
متن کاملA Submodule-Based Zero Divisors Graph for Modules
Let $R$ be commutative ring with identity and $M$ be an $R$-module. The zero divisor graph of $M$ is denoted $Gamma{(M)}$. In this study, we are going to generalize the zero divisor graph $Gamma(M)$ to submodule-based zero divisor graph $Gamma(M, N)$ by replacing elements whose product is zero with elements whose product is in some submodules $N$ of $M$. The main objective of this pa...
متن کاملOn zero divisor graph of unique product monoid rings over Noetherian reversible ring
Let $R$ be an associative ring with identity and $Z^*(R)$ be its set of non-zero zero divisors. The zero-divisor graph of $R$, denoted by $Gamma(R)$, is the graph whose vertices are the non-zero zero-divisors of $R$, and two distinct vertices $r$ and $s$ are adjacent if and only if $rs=0$ or $sr=0$. In this paper, we bring some results about undirected zero-divisor graph of a monoid ring o...
متن کاملA commutativity-or-finiteness condition for rings
In view of this result, it was conjectured that any ring with only finitely many noncentral subrings is either finite or commutative. It is our principal goal to prove this conjecture; and in the process we provide a new proof of Theorem 1.1. For any ring R, the symbols N, D, Z , and ℘(R) will denote, respectively, the set of nilpotent elements, the set of zero divisors, the center, and the pri...
متن کاملSmarandache-Zero Divisors in Group Rings
The study of zero-divisors in group rings had become interesting problem since 1940 with the famous zero-divisor conjecture proposed by G.Higman [2]. Since then several researchers [1, 2, 3] have given partial solutions to this conjecture. Till date the problem remains unsolved. Now we introduce the notions of Smarandache zero divisors (S-zero divisors) and Smarandache week zero divisors (S-wea...
