For example a graph is planar if it contains neither the complete bipartite graph K3,3 (See Three cottage problem) nor the complete graph K5. Unfortunately, finding maximal subgraphs of a certain...

... Instead of considering subdivisions, Wagner's theorem deals with minors: A finite graph is planar if and only if it does not have K5 or K3,3 as a minor. Klaus Wagner asked more generally whether any minor-closed class...
