Cubic Cayley Graphs and Snarks

open access: yes, 2014
The well-known conjecture that there are no snarks amongst Cayley graphs is considered. Combining the theory of Cayley maps with the existence of certain kinds of independent sets of vertices in arc-transitive graphs, some new partial results are obtained suggesting promising future research directions in regards to this conjecture.

Circumference of 3-connected cubic graphs

open access: yes, 2017
The circumference of a graph is the length of its longest cycles. Jackson established a conjecture of Bondy by showing that the circumference of a 3-connected cubic graph of order $n$ is $\Omega(n^{0.694})$.

The Graph Curvature Calculator and the curvatures of cubic graphs

open access: yes, 2017
We classify all cubic graphs with either non-negative Ollivier-Ricci curvature or non-negative Bakry-\'Emery curvature everywhere. We show in both curvature notions that the non-negatively curved graphs are the prism graphs and the M\"obius ladders.

Cubic graphs with large circumference deficit [PDF]

open access: yes, 2013
The circumference $c(G)$ of a graph $G$ is the length of a longest cycle. By exploiting our recent results on resistance of snarks, we construct infinite classes of cyclically $4$-, $5$- and $6$-edge-connected cubic graphs with circumference ratio $c(G)/|

On the skewness of the generalized Heawood graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
By the skewness of a graph, we mean the minimum number of its edges whose deletion results in a planar graph. We determine the skewness of a large family of cubic bipartite graphs (which includes the Heawood graph as a special case).

Generalized connectivity in cubic fuzzy graphs with application in the trade deficit problem

open access: yesFrontiers in Physics
Cubic fuzzy graphs (CFGs) offer greater utility as compared to interval-valued fuzzy graphs and fuzzy graphs due to their ability to represent the degree of membership for vertices and edges using both interval and fuzzy number forms. The significance of

On Independent Domination in Planar Cubic Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
A set S of vertices in a graph G is an independent dominating set of G if S is an independent set and every vertex not in S is adjacent to a vertex in S.
