Kazimierz Kuratowski Polish pronunciation: The special case of cubic planar graphs for which the only minimal forbidden subgraph is Topologja 3,3 was also independently proved by Karl Menger in Additionally, subdividing a graph cannot turn a nonplanar graph into a planar graph: Planar graphs Theorems in graph theory.
The most valuable results, which were obtained by Kazimierz Kuratowski after the war are those that concern the relationship between topology and analytic functions theoryand also research in the field of cutting Euclidean spaces.
From Wikipedia, the free encyclopedia. The extraction of these subgraphs is needed, e. It states that a finite graph is planar if and only if it does not contain a 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.

One was devoted to an axiomatic construction of topology via the closure axioms. Equivalently, a finite graph is planar if and only if it does not contain a subgraph that is homeomorphic to K 5 or K 3,3. Shopbop Designer Fashion Brands. English Choose a language for shopping.

Every Kuratowski subgraph is a special case of a minor of the same type, and while the reverse is not true, it is not difficult to find a Kuratowski subgraph of one type or the other from one of these two forbidden minors; therefore, these two theorems are equivalent.
