Polychromatic Hamilton cycles

open access: yesDiscrete Mathematics, 1993
If the complete graph on \(n\) vertices is edge-colored such that the number of times that a color may occur is less than \(cn/\log(n)\), where \(c\) is a fixed constant, then there is a Hamiltonian cycle in which no two edges have the same color.

Hamilton-connected properties in cartesian product [PDF]

open access: yesTransactions on Combinatorics, 2012
In this paper, we investigate a problem of finding natural condition to assure the product of two graphs to be hamilton-connected. We present some sufficient and necessary conditions for $GBox H$ being hamilton-connected when $G$ is a hamilton-connected ...

Rainbow Hamilton Cycles in Uniform Hypergraphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
Let $K_n^{(k)}$ be the complete $k$-uniform hypergraph, $k\ge3$, and let $\ell$ be an integer such that $1\le \ell\le k-1$ and $k-\ell$ divides $n$. An $\ell$-overlapping Hamilton cycle in $K_n^{(k)}$ is a spanning subhypergraph $C$ of  $K_n^{(k)}$  with $n/(k-\ell)$ edges and such that for some cyclic ordering of the vertices each edge of $C$ consists

Edge condition for hamiltonicity in balanced tripartite graphs [PDF]

open access: yesOpuscula Mathematica, 2009
A well-known theorem of Entringer and Schmeichel asserts that a balanced bipartite graph of order \(2n\) obtained from the complete balanced bipartite \(K_{n,n}\) by removing at most \(n-2\) edges, is bipancyclic.

Perfect Set of Euler Tours of Kp,p,p

open access: yesDiscussiones Mathematicae Graph Theory, 2016
Bermond conjectured that if G is Hamilton cycle decomposable, then L(G), the line graph of G, is Hamilton cycle decomposable. In this paper, we construct a perfect set of Euler tours for the complete tripartite graph Kp,p,p for any prime p and hence ...

On Hamilton decompositions of infinite circulant graphs [PDF]

open access: yes, 2017
The natural infinite analogue of a (finite) Hamilton cycle is a two-way-infinite Hamilton path (connected spanning 2-valent subgraph). Although it is known that every connected 2k-valent infinite circulant graph has a two-way-infinite Hamilton path ...

Rainbow hamilton cycles in random graphs [PDF]

open access: yesRandom Structures & Algorithms, 2013
AbstractOne of the most famous results in the theory of random graphs establishes that the threshold for Hamiltonicity in the Erdős‐Rényi random graph Gn,p is around . Much research has been done to extend this to increasingly challenging random structures.

Hamilton cycles in almost distance-hereditary graphs

open access: yesOpen Mathematics, 2016
Let G be a graph on n ≥ 3 vertices. A graph G is almost distance-hereditary if each connected induced subgraph H of G has the property dH(x, y) ≤ dG(x, y) + 1 for any pair of vertices x, y ∈ V(H).

Hyper-Hamiltonian circulants

open access: yesElectronic Journal of Graph Theory and Applications, 2021
A Hamiltonian graph G = (V,E) is called hyper-Hamiltonian if G-v is Hamiltonian for any v ∈ V(G). G is called a circulant if its automorphism group contains a |V(G)|-cycle.
