We first show that if a 2-connected graph G of order n is such that for each two vertices u and v such that δ = d(u) and d(v) n/2 the edge uv belongs to E(G), then G is hamiltonian. Next, by using this result, we prove that a graph G satysfying the above condition is either pancyclic or isomorphic to K_n/2,n/2.
Keywords:
hamiltonian graphs, pancyclic graphs, cycles
