2015 seminar talk: Properties intermediate between master and strong master

Talk held by David Chodounský (Academy of Sciences of the Czech Republic) at the KGRC seminar on 2015‑07‑09.

Abstract

In our recent joint work J. Zapletal, we explored a portfolio of forcing properties, which are based on the notion of a Φ-master condition. Being Φ-master is in general a property intermediate between being a master and strongly master condition (in the sense of Mitchell). The main example is the so called Y-master condition, which gives rise to the Y-proper forcing notions. This approach enables us uncovers some new interesting techniques with useful applications.
