Abstract:G is almost locally connected if B(G) is an independent set and for any x is an element of B(G), there is a vertex y in V(G)\{x} such that N(x) boolean OR {y} induces a connected subgraph of G, where B(G) denotes the set of vertices of G that are not locally connected. In this paper, we prove that an almost locally connected claw-free graph on at least 4 vertices is Hamilton-connected if and only if it is 3-connected. This generalizes a result by Asratian that a locally connected claw-free graph on at least 4 vertices is Hamilton-connected if and only if it is 3-connected [Journal of Graph Theory 23 (1996) 191-201].
