## Abstract The prism over a graph __G__ is the Cartesian product __G__ β‘ __K__~2~ of __G__ with the complete graph __K__~2~. If __G__ is hamiltonian, then __G__β‘__K__~2~ is also hamiltonian but the converse does not hold in general. Having a hamiltonian prism is shown to be an interesting relaxati

β¦ Synopsis
The edges of the complete graph K, are coloured so that no colour appears more than k = k(n) times, k=rn/(A In n)l, for some sufficiently large A. We show that there is always a Hamiltonian cycle in which each edge is a different colour. The proof technique is probabilistic.

Let G be a connected graph on n vertices. A spanning tree T of G is called an independence tree, if the set of end vertices of T (vertices with degree one in T ) is an independent set in G. If G has an independence tree, then Ξ± t (G) denotes the maximum number of end vertices of an independence tree
## Abstract Let __G__ be a graph on __n__ vertices and __N__~2~(__G__) denote the minimum size of __N__(__u__) βͺ __N__(__v__) taken over all pairs of independent vertices __u, v__ of __G__. We show that if __G__ is 3βconnected and __N__~2~(__G__) β©Ύ Β½(__n__ + 1), then __G__ has a Hamilton cycle. We
## Abstract We show that a directed graph of order __n__ will contain __n__βcycles of every orientation, provided each vertex has indegree and outdegree at least (1/2 + __n__^β1/6^)__n__ and __n__ is sufficiently large. Β© 1995 John Wiley & Sons, Inc.
