Abstract

We will discuss Shelah's proof that, in an NIP theory, a (type) definable group has a minimal type-definable subgroup of bounded index. My explanation will derive from the expositions in both Shelah's paper "Minimal bounded index subgroup for dependent theories" and the exposition in "Groups, measures, and the NIP" -- Hrushovski, Peterzil, Pillay.

There will be tea to at 3:00. The seminar begins shortly thereafter. Both graduate students and faculty are welcome to attend.
