On the maximum genus of a graph
WebThe importance of !(G) is in that the maximum genus of a graph is usually determined by calculating !. In particular, a graph G is upper embeddable if and only if !(G)˛1 where !(G)=0 or 1 depending on whether ;(G) is even or odd, respectively. A graph G whose deficiency is 2 or larger will be called a deficient graph; in other words, a WebAbstractNot all rational numbers are possibilities for the average genus of an individual graph.
