Proof of a conjecture on hamiltonian-connected graphs

Combinatorics 2021-12-01 v2

Abstract

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, Broersma, Wang and Zhang in 2020.
