Gloria Tabarelli - PhD in Mathematics, University of Trento

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
