关于图的动态染色

On Dynamic Coloring of Graphs

Meysam Alishahi

摘要:

图$G$的动态着色是一种适当的着色,使得对于度至少为2的每个顶点$v\in V(G)$,$v$的邻居接收至少2种颜色。本文给出了图的动态色数的一些上界。在这方面,我们将证明,有一个常数$c$,使得对每个$k$ -正则图$G$,$χ_d(G)\leq χ(G)+ c\ln k +1$。同时,我们也给出了正则图的动态表色数的一个上界。

英文摘要:

A dynamic coloring of a graph $G$ is a proper coloring such that for every vertex $v\in V(G)$ of degree at least 2, the neighbors of $v$ receive at least 2 colors. In this paper we present some upper bounds for the dynamic chromatic number of graphs. In this regard, we shall show that there is a constant $c$ such that for every $k$-regular graph $G$, $χ_d(G)\leq χ(G)+ c\ln k +1$. Also, we introduce an upper bound for the dynamic list chromatic number of regular graphs.
