Representations of dynamical systems on Banach spaces
Abstract:
I will discuss a the following trinity: (i) dynamical systems, (ii) their enveloping semigroups and (iii) their representations on Banach spaces.

Special Meeting
Friday October 8
3:30 - 4:30 pm
Room 230
Norbert Sauer (Calgary)
Introduction to homogeneous structures and their partitions
Abstract:
The first part of the talk will be a basic introduction to Fraisse limits and their partition problems. Then the partial order of type sets, orbits, of their automorphism groups will be introduced and its connection to partitions of the structures explained.  The connection to more recent work of Pestov and Kechris, Pestov, Todorcevic will touched on and the special case of metric spaces discussed. In the talk some of the basic tools needed for work in partition theory  
will be introduced.

Vladimir Pestov (Universite d'Ottawa)
Non-locally compact Polish groups: some examples, techniques, results, and open problems, I

Abstract:
Topological groups which are not locally compact feature quite prominently in various parts of mathematics. Examples are the unitary groups of Hilbert spaces, infinite symmetric groups, groups of isometries of non locally compact metric spaces (such as the Urysohn space), groups of homeomorphisms, and so forth.

The properties of such groups are, predictably, not the same as of their locally compact counterparts, and quite often in the locally compact case they are either trivially true or trivially false. In this small survey we will try to paint the picture of the present state of the study of such groups, putting an emphasis on concrete examples. In tune with the topic of the thematic program, we will pay a special attention to the role played by concentration of measure, (finite) oscillation stability, and Ramsey theory.
