摘要:


        本文给出了图的两个关于点的邻域限制标号的定义:非完全邻域限制标号SN(p,q)与完全邻域限制标号TN(p,q)SN(p,q)标号是仅对图的大度点的邻域做限制的正常标号;TN(p,q)标号是对图的所有点的邻域做限制的正常标号。图G的非完全邻域限制标号数与完全邻域限制标号数分别记为SLp,q(G),TLp,q(G)。本文主要给出了某些图G的SLp,q(G),TLp,q(G)的界。

Abstract:

       This paper presents two definitions for neighborhood restrictions labels of a graph, semitotal neighborhood restrictions label SN(p,q) and total neighborhood restrictions label TN(p,q).SN(p,q) is a normal label that only restricts the neighborhood of part dots.TN(p,q) is a normal label that restricts the neighborhood of all dots. Semitotal neighborhood restrictions label number and total neighborhood restrictions label number of a graph G are SLp,q(G) and TLp,q(G).This paper gives the bounds of SLp,q(G) and TLp,q(G) of some graphs.

Key words: semitotal neighborhood restrictions label, total neighborhood restrictions label, complete graph, bipartite graphs
