摘要: 研究了2个七点七边图的图分解, 首先利用带洞图分解给出图分解存在的递归构造, 然后利用差方法构造出递归构造中所需的图分解, 最后给出了图分解的存在谱.

Abstract: G-decomposition of λKv into graphs with seven vertices and seven edges were discussed. First, we gave a recursive structure by holy graph decomposition, and then constructed the graph decompositions wanted in recursive structure using difference method. Finally, we determined the existence spectrum of graph decomposition.

Key words: graph decomposition, holy graph decomposition, difference method
