چکیده

We study the stability of some classes of graphs deened in terms of forbidden sub-graphs under the closure operation introduced by the second author. Using these results, we prove that every 2-connected claw-free and P 7-free, or claw-free and Z 4-free, or claw-free and eiiel-free graph is either hamiltonian or belongs to a certain class of exceptions (all of them having connectivity 2).

Forbidden subgraphs, stability and hamiltonicity

We study the stability of some classes of claw-free graphs deened in terms of forbidden subgraphs under the closure operation deened in 10]. We characterize all connected graphs A such that the class of all CA-free graphs (where C denotes the claw) is stable. Using this result, we prove that every 2-connected and CHP 8-free, CHZ 5-free or CHN 1;1;4-free graph is either hamiltonian or belongs to...

Recent research in Graph Theory

A well-known and fundamental property of graphs is Hamiltonicity. A connected graph is Hamiltonian if it contains a spanning cycle. Determining if a graph is Hamiltonian is known as a NP-complete problem and no satisfactory characterization exists. Nevertheless, many sufficient conditions for Hamiltonicity were found, usually expressed in terms of degree, connectivity, density, toughness, indep...

Forbidden Subgraphs for Hamiltonicity of 3-Connected Claw-Free Graphs

In this paper, we consider forbidden subgraphs for hamiltonicity of 3-connected claw-free graphs. Let Zi be the graph obtaind from a triangle by attaching a path of length i to one of its vertices, and let Q∗ be the graph obtained from the Petersen graph by adding one pendant edge to each vertex. Lai et al. [J. Graph Theory 64 (2010), no. 1, 1-11] conjectured that every 3-connected {K1,3, Z9}-f...

On a Closure Concept in Claw-Free Graphs

If G is a claw-free graph, then there is a graph cl(G) such that (i) G is a spanning subgraph of cl(G), (ii) cl(G) is a line graph of a triangle-free graph, and (iii) the length of a longest cycle in G and in cl(G) is the same. A suucient condition for hamiltonicity in claw-free graphs, the equivalence of some conjectures on hamiltonicity in 2-tough graphs and the hamiltonicity of 7-connected c...
