Ari Brodsky: Distributive Aronszajn trees
Place: Fields Institute (Room 210)
Date: April 21, 2017 (13:3015:00)
Speaker: Ari Brodsky, BarIlan 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…

Date: October 28, 2016 (13:3015:00)
Speaker: Ari Brodsky, BarIlan University
Title: More notions of forcing add a Souslin tree
Abstract: Shelah proved that Cohen forcing adds an $\omega_1$Souslin tree. continue reading…

BGU Seminar in Logic, Set Theory and Topology.
Time: Tuesday, May 24th, 12:3013:45.
Place: Seminar room 101, Math building 58.
Speaker: Ari Brodsky (BIU).
Title: Custommade 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…
