Ari Brodsky: Distributive Aronszajn trees
Place: Fields Institute (Room 210)
Date: April 21, 2017 (13:30-15:00)
Speaker: Ari Brodsky, Bar-Ilan University
Title: Distributive Aronszajn trees
Abstract: We address a conjecture asserting that, assuming GCH, for every singular cardinal $\lambda$, if there exists a $\lambda^+$-Aronszajn tree, then there exists one which is moreover $\lambda$-distributive.A major component of this work is the study of postprocessing functions and their effect on square sequences. continue reading…

Speaker: Ari Brodsky, Bar-Ilan University
Title: More notions of forcing add a Souslin tree
Abstract: Shelah proved that Cohen forcing adds an $\omega_1$-Souslin tree. continue reading…
Ari Brodsky: Custom-made Souslin trees
BGU Seminar in Logic, Set Theory and Topology.

Place: Seminar room -101, Math building 58.
Speaker: Ari Brodsky (BIU).
Title: Custom-made Souslin trees
Abstract:
We propose a parameterized proxy principle from which $\kappa$-Souslin trees with various additional features can be constructed, regardless of the identity of $\kappa$. continue reading…
