Jan Hladký, Invitation to graphons
January 25 Wednesday @ 4:30 PM - 5:30 PM KST
The first course in graph theory usually covers concepts such as matchings, independent sets, colourings, and forbidden subgraphs. Around 2004, Borgs, Chayes, Lovász, Sós, Szegedy, and Vestergombi introduced a very fruitful limit perspective on graphs. The central objects of this theory, so-called graphons, are suitable measurable counterparts to graphs. In the talk, I will outline the syllabus of a hypothetical first course in graphon theory, in particular introducing versions of all the aforementioned concepts in the graphon setting. Based on work with Doležal, Hu, Máthé, Piguet, Rocha.
