摘要:

给出整数序列^c(d₁,d₂,…,d_n)蕴含K_1,4+2e可图的1个充分条件和1个充要条件,其中K_1,4+2e是向完全二部图K_1,4添加2条边后构成的简单图.

Abstract:

A sufficient condition and a necessary and sufficient condition are presented in this paper for the positive integer sequences ^c (d₁, d₂, …, d_n), which is potentially k_{1, 4}+2e-graphic, where the k_{1, 4}+2e is the complete bipartite graph k_{1, 4} to be added two edges.
