2020 seminar talk: Preserving splitting families

Talk held by Diego Mejía (Shizuoka University, Japan) at the KGRC seminar on 2020-05-28.


We present a method to force splitting families that can be preserved by a large class of finite support iterations of ccc posets. As an application, we show how to force several cardinal characteristics of the continuum to be pairwise different.

This is a joint work with Martin Goldstern, Jakob Kellner and Saharon Shelah.

The slides for this talk are available.
