有关循环图C(n;{1,k})的独立数的一些结果(英文)
Some Results on the Independence Number of Circulant Graphs C(n;{1,k})
【摘要】 令G=(V(G),E(G))是一个简单有限无向图.如果V(G)的子集S中任意两个顶点均不相邻,则S是图G的一个独立集.顶点独立集大小的最大值,称为图G的独立数,记作α(G).本文研究了循环图C(n;{1,k})的独立数问题,并给出了当k=2,3,4,5时的准确值.
【Abstract】 Let G =(V(G),E(G)) be a simple finite undirected graph.A set S(?) V(G) is an independent set if no two vertices of S are adjacent.The independence numberα(G) is the maximum cardinality of an independent set in G.In this paper,we study the independence number of the circulant graphs,and give the exact values of C(n;{1,k}) for k = 2,3,4,5.
