We show that in any graph G on n vertices with d(x) + d(y) n for any two nonadjacent vertices x and y, we can fix the order of k vertices on a given cycle and find a hamiltonian c...

The domatic number of a graph G is the maximum number of dominating sets into which the vertex set of G can be partitioned. We show that the domatic number of a random r-regular g...

It was shown by Abrham that the number of pure Skolem sequences of order n, n 0 or 1 (mod 4), and the number of extended Skolem sequences of order n, are both bounded below by 2 ...
