Abstract

A simple graphoidal cover of a semigraph  is a graphoidal cover  of  such that any two paths in  have atmost one end vertex in common. The minimum cardinality of a simple graphoidal cover of  is called the simple graphoidal covering number of a semigraph and is denoted by . A simple acyclic graphoidal cover of a semigraph  is an acyclic graphoidal cover  of  such that any two paths in  have atmost one end vertex in common. The minimum cardinality of a simple acyclic graphoidal cover of  is called the simple acyclic graphoidal covering number of a semigraph and is denoted by . In this paper we find the simple acyclic graphoidal covering number for wheel in a semigraph, unicycle in a semigraph and zero-divisor graph.

半图上的简单无环图面覆盖数
半图的简单graph - like cover是这样一种graph - like cover,即图中的任意两条路径至少有一个共同的端点。的简单图形覆盖的最小基数称为半图的简单图形覆盖数,表示为。半图的简单无环图盖是这样的一种无环图盖:图中的任意两条路径几乎有一个共同的端点。的简单无环图形覆盖的最小基数称为半图的简单无环图形覆盖数,表示为。本文给出了半图中的车轮、半图中的独轮车和零因子图的简单无环图面覆盖数。
