In this note we point out a flaw in the separator theorem for rooted directed vertex graphs due to C. L. Monma and V. K. Wei (1986, J. Combin. Theory Ser. B 41, 141 181), and present a modified separator theorem for the same class of graphs.
The average orientable genus of graphs has been the subject of a considerable number of recent investigations. It is the purpose of this article to examine the extent to which the average genus of the amalgamation of graphs fails to be additive over its constituent subgraphs. This discrepancy is bou
