The maximum degree of planar graphs I. Series-parallel graphs
arXiv:1008.5361
Abstract
We prove that the maximum degree $Î_n$ of a random series-parallel graph with $n$ vertices satisfies $Î_n/\log n \to c$ in probability, and $\mathbb{E}\, Î_n \sim c \log n$ for a computable constant $c>0$. The same result holds for outerplanar graphs.
