Algebra Seminar talk

Martin Goldstern
Cichoń's Diagram and set-theoretic universes


In part 1 of my talk, I described Cichoń's Diagram, which describes a partial order between 10 uncountable cardinals, among them

In this part, I will continue to talk a bit about the cardinals in Cichoń's Diagram and hint at the methods which allow us to control/manipulate their values.

This talk is again aimed at a general mathematical audience, with no prior knowledge of ZFC-models or forcing.
