Please join us for our regular reminder-and-celebration-of-our-humanity at the Emerson Hall Poetry Night!
If you're a newcomer, the basic idea is this: people sign up for ten-minute slots during which they can read their own poetry or any other poetry that they really like (or really, anything creative that has poetic qualities).
So, come to read or just to listen! And bring your significant other, friend, family members, etc. People from all departments are welcome. There will be drinks and snacks, good poetry and excellent company. We hope to see you there!
Maryanthe Malliaris (University of Chicago) "Comparing the complexity of unstable theories"
In 1967 Keisler posed the problem of Keisler’s order, a suggested program for comparing the complexity of classes of mathematical structures using an asymptotic (ultrapower) point of view. The talk will be about recent results in this area, due to Malliaris and to Malliaris and Shelah, which advance this program by developing a sort of fine structure theory for pseudofinite behavior in model theory. In particular, the focus will be on simple theories, a key model-theoretic...
On October 30th, Steven Pinker (FAS/Psychology) and Susanna Siegel (FAS/Philosophy) will discuss the relationship between science and the humanities. The event will be moderated by Anne Harrington (FAS/History of Science).
This event is organized by the Mind/Brain/Behavior Graduate Student Committee
Joan Bagaria (Universitat de Barcelona) "Reflection phenomena in the set-theoretic universe"
The phenomenon of reflection occurs at different layers of the set-theoretic universe V, and strengthened forms of reflection associated to each layer give rise to natural additional axioms for set theory of different sorts. In this talk we shall review some strong forms of reflection pertaining to different layers such as the class of ordinals, some inner models, V itself, and even the ideal extensions of V provided by the forcing method, while exposing some intriguing...
