Families of small regular graphs of girth 7

M. Abreu, G. Araujo-Pardo, C. Balbuena +2

The first known families of cages arised from the incidence graphs of generalized polygons of order $q$ , $q$ a prime power. In particular, $(q + 1, 6)$ --cages have been obtained from…

Biregular cages of girth five

M. Abreu, G. Araujo-Pardo, C. Balbuena +2

Let $2 \leq r < m$ and $g$ be positive integers. An $(r, m; g)$ --graph} (or biregular graph) is a graph with degree set $r, m$ and girth $g$ , and an $(r, m; g)$ -cage (or biregular…

Odd 2-factored snarks

M. Abreu, D. Labbate, R. Rizzi +1

A {\em snark} is a cubic cyclically 4-edge connected graph with edge chromatic number four and girth at least five. We say that a graph $G$ is {\em odd 2-factored} if for each 2-fa…
