The Automorphism Group of $N U (3, q^{2})$

Federico Romaniello, Valentino Smaldore

Let $H (n, q^{2})$ be a non-degenerate Hermitian variety of $P G (n, q^{2})$ , $n \geq 2$ . Let $N U (n + 1, q^{2})$ be the graph whose vertices are the points of $P G (n, q^{2}) ∖ H (n, q^{2})$ and…

Betwixt and between 2-factor Hamiltonian and Perfect-Matching-Hamiltonian graphs

Federico Romaniello, Jean Paul Zerafa

A Hamiltonian graph is 2-factor Hamiltonian (2FH) if each of its 2-factors is a Hamiltonian cycle. A similar, but weaker, property is the Perfect-Matching-Hamiltonian property (PMH…

Perfect matchings, Hamiltonian cycles and edge-colourings in a class of cubic graphs

Marién Abreu, John Baptist Gauci, Domenico Labbate +2

A graph $G$ has the Perfect-Matching-Hamiltonian property (PMH-property) if for each one of its perfect matchings, there is another perfect matching of $G$ such that the union of t…
