图的拓扑可加集标号的研究

A Study on Topological Integer Additive Set-Labeling of Graphs

N. K. Sudev, K. A. Germina

摘要:

图$G$的集合标号是一个内射函数$f:V(G)\to \mathcal{P}(X)$,其中$X$是一个有限集合,$G$的集合索引子是一个集合标号,使得由$f^{\oplus}(uv) = f(u){\oplus}f(v)$对每个$uv{\in} E(G)$定义的导出函数$f^{\oplus}:E(G)\to \mathcal{P}(X)-\{\emptyset\}$也是内射的.设$G$是一个图,$X$是一个非空集.如果$f(V(G))$是$X$的一个拓扑,则集合索引器$f:V(G)\to \mathcal{P}(X)$称为$G$的一个拓扑集合标记。整数加性集合标号是一个单射函数$f:V(G)\to \mathcal{P}(\mathbb{N}_0)$,其相关函数$f^+:E(G)\to \mathcal{P}(\mathbb{N}_0)$由$f(uv)=f(u)+f(v), uv\in E(G)$定义,其中$\mathbb{N}_0$是所有非负整数的集合,$\mathcal{P}(\mathbb{N}_0)$是它的幂集。整数加性集合索引器是整数加性集合标记,使得由$f^+ (uv) = f(u)+ f(v)$定义的导出函数$f^+:E(G) \to \mathcal{P}(\mathbb{N}_0)$也是单射的。本文将图的拓扑集标号的概念推广到图的拓扑整数可加集标号。

英文摘要:

A set-labeling of a graph $G$ is an injective function $f:V(G)\to \mathcal{P}(X)$, where $X$ is a finite set and a set-indexer of $G$ is a set-labeling such that the induced function $f^{\oplus}:E(G)\to \mathcal{P}(X)-\{\emptyset\}$ defined by $f^{\oplus}(uv) = f(u){\oplus}f(v)$ for every $uv{\in} E(G)$ is also injective. Let $G$ be a graph and let $X$ be a non-empty set. A set-indexer $f:V(G)\to \mathcal{P}(X)$ is called a topological set-labeling of $G$ if $f(V(G))$ is a topology of $X$. An integer additive set-labeling is an injective function $f:V(G)\to \mathcal{P}(\mathbb{N}_0)$, whose associated function $f^+:E(G)\to \mathcal{P}(\mathbb{N}_0)$ is defined by $f(uv)=f(u)+f(v), uv\in E(G)$, where $\mathbb{N}_0$ is the set of all non-negative integers and $\mathcal{P}(\mathbb{N}_0)$ is its power set. An integer additive set-indexer is an integer additive set-labeling such that the induced function $f^+:E(G) \to \mathcal{P}(\mathbb{N}_0)$ defined by $f^+ (uv) = f(u)+ f(v)$ is also injective. In this paper, we extend the concepts of topological set-labeling of graphs to topological integer additive set-labeling of graphs.
