Yair Hayut - Stationary reflection at $\aleph_{\omega+1}$

Talk held by Yair Hayut (Hebrew University of Jerusalem, Israel) at the KGRC seminar on 2018-05-17. Abstract: Stationary reflection is one of the basic prototypes of reflection phenomena, and its failure is related to many counterexamples for compactness properties (such as almost free non-free abelian groups, and more). In 1982, Magidor showed that it ...
