潜在$K_{2,5}$ -可图序列的一个特征

A Characterization On Potentially $K_{2,5}$-graphic Sequences

Lili Hu, Chunhui Lai

摘要:

对于给定的图$H$,如果存在包含$H$作为子图的$π$的实现,则称图序列$π=(d_1,d_2,...,d_n)$是潜在$H$ -图的.设$K_m-H$是从$K_m$通过去除边集$E(H)$而获得的图,其中$H$是$K_m$的子图。本文刻画了潜在$K_{2,5}$ -可图序列.这一特征意味着Yin等人[26]的定理的特殊情况。

英文摘要:

For given a graph $H$, a graphic sequence $π=(d_1,d_2,...,d_n)$ is said to be potentially $H$-graphic if there exists a realization of $π$ containing $H$ as a subgraph. Let $K_m-H$ be the graph obtained from $K_m$ by removing the edges set $E(H)$ where $H$ is a subgraph of $K_m$. In this paper, we characterize potentially $K_{2,5}$-graphic sequences. This characterization implies a special case of a theorem due to Yin et al. [26].
