Abstract:
In this seminar the notions of filter and ultrafilter on a set introduced and their basic properties are discussed. Then it is shown how the notion of ultrafilter can be used to prove the Erdös-De Bruijin's theorem and the Hindman's theorem.
Supervisor: Stefano Baratella
The seminar corresponds to the final exam of "Set Theory", a planned course within Tabarelli Gloria’s first year PHD study programme
