On zero divisors and prime elements of po-semirings

Tongsuo Wu, Dancheng Lu, Yuanlin Li

A semiring is an algebraic structure similar to a ring, but without the requirement that each element must have an additive inverse. A po-semiring is a semiring equipped with a com…

Sub-semigroups determined by the zero-divisor graph

Tongsuo Wu, Dancheng Lu

In this paper we study sub-semigroups of a zero-divisor semigroup $S$ determined by properties of the zero-divisor graph $Γ (S)$ . We use these sub-semigroups to study the correspond…

The structures of a class of $Z$ -local rings

Tongsuo Wu, Dancheng Lu

A local ring $R$ is called $Z$ -local if $J (R) = Z (R)$ and $J (R)^{2} = 0$ . In this paper the structures of a class of $Z$ -local rings are determined.
