Eulerian $k$-dominating reconfiguration graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
For a graph $G$, the vertices of the $k$-dominating graph, denoted $\mathcal{D}_k(G)$, correspond to the dominating sets of $G$ with cardinality at most $k$. Two vertices of $\mathcal{D}_k(G)$ are adjacent if and only if the corresponding dominating sets

On factors of 4-connected claw-free graphs [PDF]

open access: yes, 1999
We consider the existence of several different kinds of factors in 4-connected claw-free graphs. This is motivated by the following two conjectures which are in fact equivalent by a recent result of the third author.

Pancyclic Cayley Graphs [PDF]

open access: yes, 2012
2010 Mathematics Subject Classification: Primary 05C25. Secondary 20K01, 05C45.Let Cay(G;S) denote the Cayley graph on a finite group G with connection set S. We extend two results about the existence of cycles in Cay(G;S) from cyclic groups to arbitrary

Cycle Partitions in Dense Regular Digraphs and Oriented Graphs

open access: yesForum of Mathematics, Sigma
A conjecture of Jackson from 1981 states that every d-regular oriented graph on n vertices with $n\leq 4d+1$ is Hamiltonian. We prove this conjecture for sufficiently large n.

Rainbow Hamilton cycles in random regular graphs

open access: yes, 2005
A rainbow subgraph of an edge-coloured graph has all edges of distinct colours. A random d-regular graph with d even, and having edges coloured randomly with d/2 of each of n colours, has a rainbow Hamilton cycle with probability tending to 1 as n tends ...

Eulerian character degree graphs of solvable groups

open access: yesAKCE International Journal of Graphs and Combinatorics
Let G be a finite group, let Irr(G) be the set of all complex irreducible characters of G and let cd(G) be the set of all degrees of characters in [Formula: see text] Let [Formula: see text] be the set of all primes that divide some degrees in [Formula ...
