Let κmax(Σ) denote the maximum value for the connectivity of any graph which embeds in the topological surface Σ. The connectivity interval for Σ is the set of integers in the interval [1, κmax(Σ)]. Given an integer i in [1, κmax(Σ)] it is a trivial problem to demonstrate that there is a graph Gi with connectivity i which also embeds in Σ. We will say that… (More)
