摘要
We investigate pairs of forbidden subgraphs that imply a 3-connected graph is Hamiltonian-connected. In particular we show that the pair {K (1,3), P (9)} is such a pair. As it is known that P (10) cannot replace P (9), this result is best possible. Further, we show that certain other graphs are not possible.
