Let G(V, E) be a simple graph, k is a positive integer. f is a mapping from V(G)∪ E(G) to {1, 2, …, k} such that ∀uvE(G), then f(u)≠f(uv), f(v)≠f(uv), C(u)≠C(v), f can be called the vertex-edge-adjacent vertex distinguishing total coloring of G (adjacent vertex distinguishing VE-total coloring of G), χatve(G)=min{k|k-VE-AVDTC} would be called the vertex-edge-adjacent vertex distinguishing total chromatic number of G (adjacent vertex distinguishing VE-total chromatic number of G), where vertex-edge-adjacent vertex distinguishing total coloring of G C(u)={f(u)}∪{f(uv)|uvE(G)}. In this paper, two kinds of crown graphs Cm·Sn and Cm·Pn are designed, the vertex-edge-adjacent vertex distinguishing total coloring of Cm·Sn and Cm·Pn are studied. According to the properties of two kinds of crown graphs Cm·Sn and Cm·Pn, by using colors one by one and in recursion, the vertex-edge-adjacent vertex distinguishing total chromatic numbers of two kinds of crown graphs Cm·Sn and Cm·Pn are obtained., authors=TIAN Jingjing, authorsList=TIAN Jingjing, authorCompany=Department of Mathematics, Shaanxi University of Technology, Hanzhong 723001,

图的染色理论是图论的一个重要研究领域,求解图的色数被认为是一个NP-hard问题。对简单连通图G(V,E),存在一个正整数k,使得映射f :V(G)∪ E(G)→{1,2,…,K},如果对∀uvE(G),有f(u)≠f(uv),f(v)≠f(uv),且C(u)≠C(v),则称f是图G的点边邻点可区别全染色(又称为邻点可区别VE-全染色),而χatve (G)=min{k|kVEAVDTC},称为G的点边邻点可区别边色数(又称为邻点可区别VE-全色数),其中色集合C(u)={f(u)}∪{f(uv)|uvE(G)}。本文构造了两类冠图Cm·SnCm·Pn,研究了两类冠图Cm·SnCm·Pn的点边邻点可区别全染色。根据Cm·SnCm·Pn的结构性质,用穷染递推的方法,得到了它们的相应色数,给出一种染色方案。

Graph coloring is one of the chief topics in the graph research, the solution of the chromatic number of the graph is an NP-hard problem. Let G(V, E) be a simple graph, k is a positive integer. f is a mapping from V(G)∪ E(G) to {1, 2, …, k} such that ∀uvE(G), then f(u)≠f(uv), f(v)≠f(uv), C(u)≠C(v), f can be called the vertex-edge-adjacent vertex distinguishing total coloring of G (adjacent vertex distinguishing VE-total coloring of G), χatve(G)=min{k|k-VE-AVDTC} would be called the vertex-edge-adjacent vertex distinguishing total chromatic number of G (adjacent vertex distinguishing VE-total chromatic number of G), where vertex-edge-adjacent vertex distinguishing total coloring of G C(u)={f(u)}∪{f(uv)|uvE(G)}. In this paper, two kinds of crown graphs Cm·Sn and Cm·Pn are designed, the vertex-edge-adjacent vertex distinguishing total coloring of Cm·Sn and Cm·Pn are studied. According to the properties of two kinds of crown graphs Cm·Sn and Cm·Pn, by using colors one by one and in recursion, the vertex-edge-adjacent vertex distinguishing total chromatic numbers of two kinds of crown graphs Cm·Sn and Cm·Pn are obtained.
