Abstract: 

This will be a continuation of Ludomir's talks about our joint paper with Pierre Simon. Ludomir presented the proofs of boundedness and absoluteness of Ellis groups of the flows of the form (Aut(C), SX(C)), where X is type-definable over the empty set and C is a monster model of a given theory. During my talks, I will focus on boundedness and absoluteness of minimal ideals of Ellis semigroups of such flows. I will also discuss some more specific results on minimal ideals and on Ellis groups in the NIP environment.
