关于潜在3-正则图图序列

On Potentially 3-regular graph 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.本文刻画了潜在$H$ -可图序列,其中$H$表示6个顶点的3-正则图.换句话说,我们刻画了潜在的$K_{3,3}$和$K_6-C_6$ -图序列,其中$K_{r,r}$是一个$r\times r$完全二部图.这些特征之一暗示了尹[25]的定理。

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. In this paper, we characterize the potentially $H$-graphic sequences where $H$ denotes 3-regular graph with 6 vertices. In other words, we characterize the potentially $K_{3,3}$ and $K_6-C_6$-graphic sequences where $K_{r,r}$ is an $r\times r$ complete bipartite graph. One of these characterizations implies a theorem due to Yin [25].
