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
## Abstract The orientable genus is determined for any graph that embeds into the projective plane, Ξ£, to be essentially half of the representativity of any embedding into Ξ£. In addition, a structure is given for any 3βconnected projective planar graph as the union of a spanning planar graph and a
