单图与交换零因子半群

Simple Graphs and Commutative Zero-Divisor Semigroups

Tongsuo Wu, Li Chen

摘要:

本文研究由图决定的交换零因子半群。证明了一类图的唯一性定理。我们证明了两类没有相应半群的图。特别地,任何具有三个以上端点的完全图$K_n$和任何具有一个以上端点的完全二部图都没有相应的半群。我们还确定了所有可能的零因子图是有两个端点的完全图$K_3$的零因子半群。

英文摘要:

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 corresponding semigroups. In particular, any complete graph $K_n$ together with more than three end vertices and any complete bipartite graph together with more than one end vertices have no corresponding semigroups. We also determine all possible zero-divisor semigroups whose zero-divisor graph is the com- plete graph $K_3$ together with two end vertices.
