摘要: |
利用收缩的方法研究了超欧拉图的欧拉生成子图的边数问题,得到了结果:若 1个超欧拉图的子图H最多差 1条边有 3棵边不交的生成树,如果把H收缩后的图满足Catlin猜想,则原图也满足Catlin猜想 . |

Abstract: |
It makes use of Reduction techniques on the problem of the edge_number of Maximam SES,and the result follows: if a graph G is supereulerian,which has a subgraph H with at most one edge short of three edge_disjoint spanning trees,then the graph G satisfies |
Key words: supereulerian graph,spanning Eulerian subgraph,reduction method,edge_number,edge_disjoint spanning tree |
