摘要: 用构造染色法和贪心算法研究限制最大度和最小度的任意两个图、 两个同阶图, 任意两个完全图的冠积与边冠积的b-色数和m-度, 以及在此基础上推出的部分图类的广义冠积和广义边冠积的b色数和m-度.

关键词: 冠积, 边冠积, b-染色, b-色数

Abstract: By using the construction of coloring method and greedy algorithm, we studied the b-coloring number and m-degree of corona product and edge corona product of any two graphs, two graphs of the same order and any two complete graphs for limit maximum and minimum degree. On the basis, we derived the b-coloring number and mdegree of the generalized corona product and edge corona product for partial graph class.

Key words: corona product, edge corona product, b-coloring, b-coloring number
