度等分图

Degree-equipartite graphs

Khodakhast Bibak, Mohammad Hassan Shirdareh Haghighi

摘要:

一个$2n$阶图$G$称为度等部图,如果对每个$n$-元素集$A\subseteq V(G)$,导出子图$G[A]$和$G[V(G)\setminus A]$的度序列相同.在本文中,我们刻画了所有的度等部图。这回答了Grünbaum等人[B. Grünbaum,T. Kaiser,D. Král和M. Rosenfeld,等分图,{\it Israel J. Math.} {\bf 168}(2008),431 - 444]。

英文摘要:

A graph $G$ of order $2n$ is called degree-equipartite if for every $n$-element set $A\subseteq V(G)$, the degree sequences of the induced subgraphs $G[A]$ and $G[V(G)\setminus A]$ are the same. In this paper, we characterize all degree-equipartite graphs. This answers Problem 1 in the paper by Grünbaum et al [B. Grünbaum, T. Kaiser, D. Král, and M. Rosenfeld, Equipartite graphs, {\it Israel J. Math.} {\bf 168} (2008), 431-444].
