If you have a question about this talk, please contact webseminars. This talk has been canceled/deleted Motivated by a conjecture of Todorcevic, we study strengthenings of the $kappa-chain$ conditions that are equivalent to the $kappa-chain$ condition in the case where $kappa$ is a weakly compact cardinal. We then use such properties to provide new characterizations of weakly compact cardinals. In addition, we show that the question whether weak compactness is characterized by the statement that all $kappa-Knaster$ posets satisfy these properties is independent from the axioms of ZFC . This is joint work with Sean D. Cox (VCU Richmond). This talk is part of the Isaac Newton Institute Seminar Series series.
