This Week in Logic at CUNY

Set Theory Seminar Friday, October 12, 2012, 10:00am GC 6417 Speaker: Nam Trang Title: GENERALIZED SOLOVAY MEASURES Abstract: We will introduce some background and recent progress made in solving the following open problem: Determine the exact consistency strength of the theory T = “ZF+DC+omega_1 is supercompact.” It’s known that the upper-bound consistency strength for T is a class of Woodin limits of Woodin cardinals which is (surprisingly) much weaker than ZFC + a supercompact. continue reading…

Nam Trang: A hierarchy of supercompactness measures in ZF+DC

Thursday, May 24, 2012, 4:00 PM RH 440R Speaker: Nam Trang (UC Berkeley) Title: A hierarchy of supercompactness measures in ZF+DC Abstract: For each $\alpha < \omega_1$, let $$X_\alpha = \{f : \omega^\alpha \rightarrow\mathcal P_{\omega_1}(\mathbb{R})\mid f\text{ is increasing and continuous}\},$$ and $\mu_\alpha$ be a normal fine measure on $X_\alpha$. continue reading…
