Edge-distance-regular graphs are distance-regular
M. Cámara, C. Dalfó, C. Delorme +2
A graph is edge-distance-regular when it is distance-regular around each of its edges and it has the same intersection numbers for any edge taken as a root. In this paper we give s…
Quadratic form representations via generalized continuants
Charles Delorme, Guillermo Pineda-Villavicencio
H. J. S. Smith proved Fermat's two-square theorem using the notion of palindromic continuants. In this paper we extend Smith's approach to proper binary quadratic form representati…
Continuants and some decompositions into squares
Charles Delorme, Guillermo Pineda-Villavicencio
In 1855 H. J. S. Smith proved Fermat's two-square using the notion of palindromic continuants. In his paper, Smith constructed a proper representation of a prime number as a su…
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…
