Trevor Wilson: Semi-scales on $\Pi^2_1$ sets

Monday, January 14, 2013, at 4pm RH 440R Speaker: Trevor Wilson (UCI) Title: Semi-scales on $\Pi^2_1$ sets Abstract: We prove a theorem of Woodin that, assuming $\mathsf{ZF} + \mathsf{AD}+ \theta_0 < \Theta$, every $\Pi^2_1$ set of reals has a semi-scale whose norms are ordinal-definable. continue reading…

14/Dec/2012: Trevor Wilson and Alex Rennet

14/December/2012, 11:o0–12:00 Fields institute,Room 230 Speaker: Trevor Wilson Title: Well-behaved measures and weak covering for derived models Abstract: For an inner model $M$ containing all the reals and satisfying the Axiom of Determinacy, we show that countably complete measures over $M$ on ordinals less than $\Theta^M$ are “well-behaved.” In particular every such measure is ordinal-definable from $M$, generalizing a theorem of Kunen that says “AD implies that every measure on an ordinal less than Theta is ordinal-definable.” This generalization is useful in constructing weak homogeneity systems consisting of measures over $M$. continue reading…

6th Young Set Theory Workshop, June 10-14, 2013

The workshop wil take place in Oropa (Piemonte-Italy) in a congress center located in a medieval sanctuary in the midst of the alpine region of north west Piemonte. The aims of the “Young Set Theory Workshops” are to bring together young researchers in the domain of set theory and give them the opportunity to learn from each other and from experts in a friendly environment. continue reading…
