27 Sep '17

Hello everyone, Today, Michelle Chu will be speaking in seminar. We will also be going to lunch today at Fuzzy's. Let's meet at the mailboxes on the 4th floor at noon. Robert is organizing that, but I will catch up with everyone after my office hours end. We are going to take Michelle to hideaway tonight at 5:30. Everyone is welcome to come to that as well. Finally, here are the title and abstract for today's talk: Title: Special subgroups of Bianchi groups Speaker: Michelle Chu, University of Texas at Austin Date: Sep 27, 2017 Time: 3:30 PM Room: MSCS 509 Abstract: The study of virtually special groups played a key role in the resolutions of some important conjectures in 3-manifold theory. In this talk I will motivate and introduce virtual properties of 3-manifold groups. I will also discuss some new results on quantifying these virtual properties for the class of Bianchi groups. ______________________ Neil R.

Today Robert is speaking in seminar his title and abstract are below: Title: Decompositions of 3-manifolds Time: 3:30 PM Room: MSCS 509 Abstract: In this introductory, expository talk, we motivate and review classical theorems of 3-manifold topology dealing with the decomposition of compact 3-manifolds along ”interesting” embedded surfaces. ______________________ Neil R.
