具有$t>1$的$t$ -坚韧图的Hamilton圈和长圈

Hamilton and long cycles in $t$-tough graphs with $t>1$

Zh. G. Nikoghosyan

摘要:

证明了:若$G$是阶为$n$且最小度为$δ$且$t>1$为$t$ -坚韧图,则$G$有一个长度至少为$\min\{n,2δ+4\}$的圈或$G$是Petersen图.

英文摘要:

It is proved that if $G$ is a $t$-tough graph of order $n$ and minimum degree $δ$ with $t>1$ then either $G$ has a cycle of length at least $\min\{n,2δ+4\}$ or $G$ is the Petersen graph.
