## 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…
