On ordered Bratteli diagrams

Wei Sun

10:00 am to 11:00 am, Nov 20th, 2013   Science Building A1510

Abstract:

In this talk, we will review the definition of Bratteli diagrams and their relation with AF-algebras. Then we will give the definition of ordered Bratteli diagrams, and the corresponding space and action related to it.

We will cover the subtle question of when the action on the above defined space is continuous (and when it might fail).

This is the first of a series of talks aiming at introducing my joint work with Zhuang Niu and Sergey Bezuglyi on certain non-simple Cantor dynamics.
