Abstract

After investigating several existing necessary and sufficient conditions, we prove that if a graph G is 1-tough with n >= 3 vertices such that d(u) + d(v) + d(w) >= max{n, n + k − 3} holds for any three independent vertices u, v, w of G, where k is the vertex connectivity, then G is Hamiltonian.
