On the orientable genus of the cartesian product of a complete regular tripartite graph with a even cycle

C. Paul Bonnington and Tomav{z} Pisanski

Abstract

We apply the technique of patchwork embeddings
to find orientable genus embeddings of the Cartesian product of a complete regular tripartite graph with a even cycle. In particular, the orientable genus of
$kc$ is
determined for $m ge 1$ and for all $n ge 3$ and $n = 1$. For $n
= 2$ both lower and upper bounds are given. We see that the resulting embeddings may have a mixture of
triangular and quadrilateral faces, in contrast to previous applications of patchwork method.
