Title:On automorphisms of saturated models of Peano Arithmetic
Seminar:Logic Seminar
Speaker:Ermek Nurkhaidarov, Pennsylvania State University, Mont Alto Campus
Abstract:
We discuss properties of automorphisms of saturated models of Peano Arithmetic. In particular we investigate the closed normal subgroups of the automorphism group of a saturated model. We show existence of saturated models of PA (of the same cardinality) with nonisomorphic automorphism groups.
