An extension of a cubic 2-connected plane graph G to a hamiltonian plane graph contained in G^{2}

Jan Florek

Let $G$ be a simple cubic 2-connected plane graph. For every $2$ -factor $X$ of $G$ having $n$ -components there exists a simple hamiltonian plane graph $J \subset G^{2}$ such that $…

Graphs with multi- $4$ -cycles and the Barnette's conjecture

Jan Florek

Let $H$ denote the family of all graphs with multi- $4$ -cycles and suppose that $G \in H$ . Then, $G$ is a bipartite graph with a vertex bipartition ${V_{α}, V_{β}}$ . We…
