Optimal orientations of vertex-multiplications of cartesian products of graphs

W. H. W. Wong, E. G. Tay

Koh and Tay proved a fundamental classification of $G$ vertex-multiplications into three classes $C_{0}, C_{1}$ and $C_{2}$ . In this paper, we prove that ve…

A complete characterisation of vertex-multiplications of trees with diameter 5

W. H. W. Wong, E. G. Tay

Koh and Tay introduced a new family of graphs, $G$ vertex-multiplications, as an extension of complete $n$ -partite graphs. They proved a fundamental classification of $G$ vertex-mu…

On optimal orientations of complete tripartite graphs

W. H. W. Wong, E. G. Tay

Given a connected and bridgeless graph $G$ , let $D (G)$ be the family of strong orientations of $G$ . The orientation number of $G$ is defined to be $\bar{d}(G):=min\{d(D)|…
