Student Working Seminar in Groups and Dynamics
Organizers:
David Carroll (carroll math.tamu.edu)
Krzysztof Swiecicki (ksas math.tamu.edu)
The Student Working Seminar in Groups and Dynamics is an informal, studentrun seminar that meets approximately
once a week to discuss topics related to group theory and dynamical systems. Talks are at the graduate/postdoctoral
level and can be presentations of original results, exposition of the literature, or simply openended
conversations. If you would like to give a talk or be added to the mailing list, please email one of the organizers.
This semester (Fall 2015), the seminar will meet weekly on Mondays from 34 PM in Blocker 624.

A Brief Introduction to 3 Dimensional Manifolds
In his celebrated work from 2003, Perelman finished the proof
of Poincare conjecture in dimension 3. His result is in fact far
stronger and implies Thurston's geometrization conjecture, which
classifies possible geometric structures on 3 manifolds. I'll give an
overview of the result and introduce all eight basic geometries and
their connection to group theory. I won't assume any knowledge outside
of basic topology, so any newcomers are welcome.

Topological full groups, amenability, and Godometers
Topological full groups were first introduced by
Giordano,Putnam, and Skau as an invariant related to orbit equivalence
for minimal cantor systems. However, more recent interest has been given
to these groups because they provide examples of groups with interesting
properties related to amenability. In this talk, I will give an overview
of some of the basic concepts of topological dynamics, as well as
introduce topological full group and the concept of amenability. The
goal is to explicitly describe the structure of the topological full
groups coming from Godometers, following a paper of Cortez and
Medynets."

Coarse embeddings under group extensions
I will be going over a paper by Arzhantseva and Tessera (2017)
which proves, by construction, that admitting a coarse embedding into
Hilbert space is not preserved under group extension.
