Equatorially balanced C4-face-magic labelings on Klein bottle grid graphs

Stephen J. Curran, Richard M. Low, Stephen C. Locke

For a graph $G=(V,E)$ embedded in the Klein bottle, let $\mathcal{F}(G)$ denote the set of faces of $G$. Then, $G$ is called a $C_k$-face-magic Klein bottle graph if there exist…
