β¦ Synopsis
Let k β₯ 2 be an integer. A k-factor F of a graph G is called a hamiltonian k-factor if F contains a hamiltonian cycle. In this paper, we shall prove that if G is a graph of order n with k β₯ 2, n β₯ 8k -4, kn even and Ξ΄(G) β₯ n/2, then G has a hamiltonian k-factor.

A hamiltonian graph G of order n is k-ordered, 2 β€ k β€ n, if for every sequence v 1 , v 2 , . . . , v k of k distinct vertices of G, there exists a hamiltonian cycle that encounters v 1 , v 2 , . . . , v k in this order.

We give a simple proof that the obvious necessary conditions for a graph to contain the k th power of a Hamiltonian path are sufficient for the class of interval graphs. The proof is based on showing that a greedy algorithm tests for the existence of Hamiltonian path powers in interval graphs. We wi
The problem is considered under which conditions a 4-connected planar or projective planar graph has a Hamiltonian cycle containing certain prescribed edges and missing certain forbidden edges. The results are applied to obtain novel lower bounds on the number of distinct Hamiltonian cycles that mus
We prove that every 18-tough chordal graph has a Hamiltonian cycle.
