On graphs with cyclic defect or excess
Charles Delorme, Guillermo Pineda-Villavicencio
The Moore bound constitutes both an upper bound on the order of a graph of maximum degree and diameter and a lower bound on the order of a graph of minimum degree and…
On graphs of defect at most 2
Ramiro Feria-Purón, Mirka Miller, Guillermo Pineda-Villavicencio
In this paper we consider the degree/diameter problem, namely, given natural numbers Δ \geq 2 and D \geq 1, find the maximum number N(Δ,D) of vertices in a graph of maximum degree…
On bipartite graphs of defect at most 4
Ramiro Feria-Purón, Guillermo Pineda-Villavicencio
We consider the bipartite version of the degree/diameter problem, namely, given natural numbers Δ \geq 2 and D \geq 2, find the maximum number Nb(Δ,D) of vertices in a bipartite gr…
