A collaboration agreement was signed in 2009 by the Universidade Federal de Santa Catarina and the University of Ottawa to account for their common interests in many areas of Mathematics, including Operator Algebras and their links to Dynamical Systems and Group Actions. This is the second meeting to take place under the auspices of this agreement (the first one being the “Extended Workshop on Groups and Group Actions in Operator Algebra Theory”, held at the University of Ottawa in July, 2010). However, these workshops are open to everyone, and everybody is welcome.

Both Sao Paulo and Rio have more than one major airport. Please make sure your connecting flight leaves from the same airport your international flight arrives at. Transferring between airports may be an unpleasant experience.
