Kuratowski's theorem
.
A graph (PL) is planar iff it contains no subgraph homeomorphic to K 5 (the complete graph on five vertices) or K 3,3 (the bipartite graph having three vertices in each vertex set). A Corollary states that a graph is planar iff it contains no subgraph contractible to K5 or K3,3 -- sometimes called "Kuratowski graphs". Technological importance: planar graphs make possible printed circuits on microchips in computers. (The Graphs.)
