this paper is an attempt to generalize, simultaneously, the ring of real-valued continuous functions and the ring of real-valued measurable functions.

In this paper, we study a special class of elements in the finite commutative rings called involutions. An involution ring R is an element with property that x^2-1=0 for some x R. This describes both implementation and enumeration involutions various rings, such as cyclic non-cyclic zero-rings, fields, especially Gaussian integers. The paper begins simple well-known results equation over It pro...

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 ov...
