Menger's Theorem
Christoph Dittmann

We present a formalization of Menger's Theorem for directed and undirected
graphs in Isabelle/HOL. This well-known result shows that if two non-adjacent
distinct vertices u, v in a directed graph have no separator smaller than n,
then there exist n internally vertex-disjoint paths from u to v. The version for
undirected graphs follows immediately because undirected graphs are a special
case of directed graphs.
