Abstract

Let [Formula: see text] be a commutative ring and [Formula: see text] be its zero-divisor graph. We completely determine the structure of all finite commutative rings whose zero-divisor graphs have clique number one, two, or three. Furthermore, if [Formula: see text] (each [Formula: see text] is local for [Formula: see text]), we also give algebraic characterizations of the ring [Formula: see text] when the clique number of [Formula: see text] is four.

图团数小于5的有限环

设[公式:见文]是一个交换环，[公式:见文]是它的零因子图。我们完全确定了所有有限交换环的结构，其零因子图具有团数1、2或3。进一步，如果[公式:见文](每个[公式:见文]都是[公式:见文]的局部)，我们也给出了当[公式:见文]的团数为4时环[公式:见文]的代数刻画。

期刊介绍： Algebra Colloquium is an international mathematical journal founded at the beginning of 1994. It is edited by the Academy of Mathematics & Systems Science, Chinese Academy of Sciences, jointly with Suzhou University, and published quarterly in English in every March, June, September and December. Algebra Colloquium carries original research articles of high level in the field of pure and applied algebra. Papers from related areas which have applications to algebra are also considered for publication. This journal aims to reflect the latest developments in algebra and promote international academic exchanges.
