Session 32. Set Theory
|
Universal minimal proximal flows of non-Archimedean Polish groups |
Lionel Nguyen Van Thé, Aix-Marseille University, France
|
The talk is based on some joint work with Julien Melleray (Lyon 1) and Todor Tsankov (Paris-Diderot)
|
|
|
Given a topological group G, certain classes of minimal G-flows admit a
unique universal element. Proximal flows fall into that category, and the
purpose of this talk will be to use the Kechris-Pestov-Todorcevic
correspondence between structural Ramsey theory and topological dynamics
to describe explicitly the universal object attached to various
non-Archimedean Polish groups.
