On k-Path Pancyclic Graphs

Similarity:

For integers k and n with 2 ≤ k ≤ n − 1, a graph G of order n is k-path pancyclic if every path P of order k in G lies on a cycle of every length from k + 1 to n. Thus a 2-path pancyclic graph is edge-pancyclic. In this paper, we present sufficient conditions for graphs to be k-path pancyclic. For a graph G of order n ≥ 3, we establish sharp lower bounds in terms of n and k for (a) the minimum degree of G, (b) the minimum degree-sum of nonadjacent vertices of G and (c) the size of G...

Bounds of lengths of open Hamiltonian walks

Pavel Vacek (1992)

Similarity:

If G is a graph, an open Hamiltonian walk is any open sequence of edges of minimal length which includes every vertex of G . In this paper bounds of lengths of open Hamiltonian walks are studied.
