This was the subject of a French doctoral thesis written by Zygmunt Janiszewski. It was applied toploogia issues such as cutting-plane, with the paradoxical examples of connected components. He was the head of kkratowski Mathematics department there until The two graphs K 5 and K 3,3 are nonplanar, as may be shown either by a case analysis or an argument involving Euler’s formula.

It states that a finite graph is planar if and only if it does not contain kruatowski subgraph that is a subdivision of K 5 the complete graph on five vertices or of K 3,3 complete bipartite graph on six vertices, three of which connect to each of the other three, also known as the utility graph.
Kuratowski’s theorem – Wikipedia
In FebruaryKuratowski started to lecture at the reopened Warsaw University. The more difficult direction in proving Kuratowski’s theorem is to show that, if a graph is nonplanar, it must contain a Kuratowski subgraph.
The extraction of these subgraphs is needed, e.
Kuratowski’s theorem states that a finite graph G is planar, if it is not possible to subdivide the edges of K 5 or K 3,3and then possibly add additional edges and vertices, to form a graph isomorphic to G.
