摘要
通过分析蛛形图的结构和计算它的组合度,利用穷举法和组合分析法研究了蛛形图的D(2)-点强可区别的全染色.通过构造具体染色,得到了蛛形图的D(2)-点强可区别的全色数.
Through structure analysis of the spider graph and calculation of its combined degree,D(2)-vertexstrongly distinguishing total coloring of the spider graph is discussed by the exhaustion method and the combinationanalytic method,through construction detail coloring of the spider graph,D(2)-vertex distinguishing total chromaticnumber of the spider graph is obtained.
