David Asperó: Special $\aleph_2$-Aronszajn trees and GCH

Talk held by David Asperó (University of East Anglia, Norwich, UK) at the KGRC seminar on 2018-10-22. Abstract: In joint work with Mohammad Golshani, and assuming the existence of a weakly compact cardinal, we build a forcing extension in which GCH holds and every $\aleph_2$-Aronszajn tree is special. continue reading…

David Aspero: Generic absoluteness for Chang models

Tuesday, March 21, 2017, 15.00 Howard House 4th Floor Seminar Room Speaker: David Aspero (University of East Anglia) Title: Generic absoluteness for Chang models Abstract: The main focus of the talk will be on extensions of Woodin’s classical result that, in the presence of a proper class of Woodin cardinals, C_omega^V and C_omega^{V^P} are elementarily equivalent for every set—forcing P (where C_kappa denotes the kappa—Chang model). continue reading…
