5连通线图中的Hamilton圈

Hamilton cycles in 5-connected line graphs

Tomáš Kaiser, Petr Vrána

摘要:

Carsten Schlassen的一个猜想指出,每个4-连通线图都是哈密尔顿的。已知该猜想对于7连通线图成立。我们通过证明任何最小度至少为6的5-连通线图是哈密尔顿的来改进这一点。结果扩展到无爪图和Hamilton连通性。

英文摘要:

A conjecture of Carsten Thomassen states that every 4-connected line graph is hamiltonian. It is known that the conjecture is true for 7-connected line graphs. We improve this by showing that any 5-connected line graph of minimum degree at least 6 is hamiltonian. The result extends to claw-free graphs and to Hamilton-connectedness.
