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

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.
