چکیده

If P is a given graph property, we say that a graph G is locally P if 〈N(v)〉 has property P for every v ∈ V (G) where 〈N(v)〉 is the induced graph on the open neighbourhood of the vertex v. Pareek and Skupień (C. M. Pareek and Z. Skupień, On the smallest non-Hamiltonian locally Hamiltonian graph, J. Univ. Kuwait (Sci.), 10:9 17, 1983) posed the following two questions. Question 1 Is 9 the smallest order of a connected nontraceable locally traceable graph? Question 2 Is 14 the smallest order of a connected nontraceable locally hamiltonian graph?

Traceability in Small Claw-Free Graphs

We prove that a claw-free, 2-connected graph with fewer than 18 vertices is traceable, and we determine all non-traceable, claw-free, 2-connected graphs with exactly 18 vertices and a minimal number of edges. This complements a result of Matthews on Hamiltonian graphs.

A Traceability Conjecture for Oriented Graphs

A (di)graph G of order n is k-traceable (for some k, 1 ≤ k ≤ n) if every induced sub(di)graph of G of order k is traceable. It follows from Dirac’s degree condition for hamiltonicity that for k ≥ 2 every k-traceable graph of order at least 2k − 1 is hamiltonian. The same is true for strong oriented graphs when k = 2, 3, 4, but not when k ≥ 5. However, we conjecture that for k ≥ 2 every k-tracea...

Simple Necessary Conditions for the Existence of a Hamiltonian Path with Applications to Cactus Graphs

We describe some necessary conditions for the existence of a Hamiltonian path in any graph (in other words, for a graph to be traceable). These conditions result in a linear time algorithm to decide the Hamiltonian path problem for cactus graphs. We apply this algorithm to several molecular databases to report the numbers of graphs that are traceable cactus graphs.

Graphs That Are Randomly Traceable from a Vertex

A graph G is randomly traceable from one of its vertices v if every path in G starting at v can be extended to a hamiltonian path of G that starts at v. A complete classification of these graphs will be given, and some corollaries will be stated. Also, a few related concepts will be briefly discussed.

Recent Advances on the Hamiltonian Problem: Survey III

This article is intended as a survey, updating earlier surveys in the area. For completeness of the presentation of both particular questions and the general area, it also contains some material on closely related topics such as traceable, pancyclic and Hamiltonian connected graphs.
