2014 seminar talk: Matrix iterations of ccc posets

Talk held by Diego Alejandro Mejía Guzmán (KGRC) at the KGRC seminar on 2014-05-08.

Abstract

We present several examples of ccc forcing constructions, using matrix iterations, to obtain models where several classical cardinal invariants of the continuum assume pairwise different values (preferably arbitrary ones). The main application is to obtain constellations of Cichon's diagram where the cardinals at the right hand side assume three different values.
