Every 3-connected {K1,3​,Γ3​}-free graph is Hamilton-connected

Adam Kabela, Zdeněk Ryjáček, Mária Skyvová +1

We show that every 3-connected {K1,3​,Γ3​}-free graph is Hamilton-connected, where Γ3​ is the graph obtained by joining two vertex-disjoint triangles with a path of lengt…

Proof of a conjecture on hamiltonian-connected graphs

Petr Vrana, Xingzhi Zhan, Leilei Zhang

We prove that every 3-connected claw-free graph with domination number at most 3 is hamiltonian-connected. The result is sharp and it is inspired by a conjecture posed by Zheng, Br…

On forbidden induced subgraphs for K_{1,3}-free perfect graphs

Christoph Brause, Přemysl Holub, Adam Kabela +3

Considering connected K1,3​-free graphs with independence number at least 3, Chudnovsky and Seymour (2010) showed that every such graph, say G, is 2ω-colourable where ω…

Hamilton cycles in 5-connected line graphs

Tomáš Kaiser, Petr Vrána

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 s…
