Ramsey theory is based on Ramsey's theorem, because without it, there would be no Ramsey numbers, since they are not well-defined. This is part 2 of the trilogy of the Ramsey numbers. Useful link: https://en.wikipedia.org/wiki/Ramsey%27s_theorem#2-colour_case Other than commenting on the

Rhapsody on Ramsey numbers (and aliens?)
Why are aliens involved in this graph theory problem? This video trilogy will investigate deep into Ramsey's theory, ultimately showing R(4,4)=18. Although this field of graph theory is pretty famous and possibly covered by many Youtube channels, this more-than-20-minute journey Other th

Using nonstandard natural numbers in Ramsey Theory - M. Di Nasso - Workshop 1 - CEB T1 2018
Mauro Di Nasso (Pisa) / 01.02.2018 In Ramsey Theory, ultrafilters often play an instrumental role. By means of nonstandard models, one can reduce those third-order objects (ultrafilters are sets of sets of natural numbers) to simple points. In this talk we present a nonstandard technique

Todor Tsankov (Université Paris Diderot) / 01.02.2018 The connection between Ramsey theory and topological dynamics goes back at least to Furstenberg who used dynamical systems of the group of integers to derive a new proof of Van Der Waerden’s theorem. More recently, Kechris, Pestov, and
