  • Abstract: My aim is to introduce you to notion of crossing numbers. Crossing numbers was introduced by Paul Turán, originally Turán was interested in one specific graph class (complete bipartite graphs) but later it was shown importance of crossing number parameter in combinatorics with many applications. I would like to show you some structural properties (Hanani-Tutte theorem), also some algorthmic aspects and in the end some application in combinatorial geometry.
