Irreducible pseudo 2-factor isomorphic cubic bipartite graphs
M. Abreu, D. Labbate, J. Sheehan
A bipartite graph is {\em pseudo 2--factor isomorphic} if all its 2--factors have the same parity of number of circuits. In \cite{ADJLS} we proved that the only essentially 4--edge…

Pseudo and Strongly Pseudo 2--Factor Isomorphic Regular Graphs
M. Abreu, D. Labbate, J. Sheehan
A graph is pseudo 2--factor isomorphic if the parity of the number of cycles in a 2--factor is the same for all 2--factors of . In \cite{ADJLS} we proved that pseudo 2--fact…

Adjacency Matrices of Configuration Graphs
M. Abreu, M. Funk, D. Labbate +1
In 1960, Hoffman and Singleton \cite{HS60} solved a celebrated equation for square matrices of order , which can be written as where $I_n…
