Title: Nonstandard Models of Arithmetic and Their Automorphism Groups

Date: Tuesday, April 14, 1998

Time: 2:30 PM

Place: 113 McAllister Building

Abstract:

I will present a survey of recent results concerning recursively
saturated models of arithmetic and their automorphism groups. In
particular I will talk about: reconstructing a model from its
automorphism group, the small index property, cofinality of the
automorphism group, and a classification of conjugacy classes.
