The Structures of Zero-divisor Semigroups with Graph Kn + 1
Tongsuo Wu, Fan Cheng
In this paper, we determine the structures of zero-divisor semigroups whose graph is , the complete graph together with an end vertex. We also present a formula to c…
Sub-semigroups determined by the zero-divisor graph
Tongsuo Wu, Dancheng Lu
In this paper we study sub-semigroups of a zero-divisor semigroup determined by properties of the zero-divisor graph . We use these sub-semigroups to study the correspond…
Simple Graphs and Commutative Zero-Divisor Semigroups
Tongsuo Wu, Li Chen
In this paper, we study commutative zero-divisor semigroups determined by graphs. We prove a uniqueness theorem for a class of graphs. We show two classes of graphs that have no co…
The structures of a class of -local rings
Tongsuo Wu, Dancheng Lu
A local ring is called -local if and . In this paper the structures of a class of -local rings are determined.
