How many edges in k3 3

• Given a bipartite graph, testing whether it contains a complete bipartite subgraph Ki,i for a parameter i is an NP-complete problem. • A planar graph cannot contain K3,3 as a minor; an outerplanar graph cannot contain K3,2 as a minor (These are not sufficient conditions for planarity and outerplanarity, but necessary). Conversely, every nonplanar graph contains either K3,3 or the complete graph K5 as a minor; this is Wagner's theorem. Web100% (2 ratings) Transcribed image text: 1.
