Internal conference
by Hoffman, Neil 23 May '18

23 May '18

Hello everyone, As you all know, Bus is stepping down as chair on June 30th. So to celebrate we were thinking of having a mini-conference July 22-23. We were going to focus on layered solid handlebodies, which Bus will be speaking about. Robert and I will be speaking about layered solid tori and bi-twist manifolds. We would also be happy if grad students got involved and volunteered to give a talk or too. For example, it would be cool to have someone do a short presentation on using regina and we might have a working afternoon where we try to program up a layered solid handlebody triangulation generator. Contact me if you are interested in joining us. Best, Neil ______________________ Neil R.

Eric's talk today
by Hoffman, Neil 02 May '18

02 May '18

Hello topologists, Today at 3:30 in MSCS 445, Eric will be presenting in topology seminar as part of his qualifying exam. His title and abstract are below. Title: More infinite families of homology lens spaces of lower bounded complexity Abstract: We replicate a computation of Boyer and Lines [BL90] concerning closed orientable 3-manifolds, exhibiting infinitely many prime integral homology lens spaces, M, such that M is obtained by p/q Dehn surgery along a knot in an integral homology sphere, but M cannot be obtained by such a surgery along any knot in the 3-sphere. We then demonstrate additional families of such spaces. Notes: This is a qualifying exam. ______________________ Neil R.
