NIP Theories and Definable Subgroups
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"
