Topology and Group Theory Seminar: April 16, 2025
Mar. 9, 2025—Speaker: Robbie Lyman (Rutgers) Title: Graphical models for groups Abstract: In geometric group theory, we love groups and graphs. Every (abstract) group has (many) Cayley graphs, each one associated with a choice of a generating set. Recently I’ve been curious about topological groups, inspired by the budding theory around and community of people inspired by mapping class...
Topology and Group Theory Seminar: April 9, 2025
Mar. 9, 2025—Speaker: John Ratcliffe (Vanderbilt) Title: The G-index of a spin closed hyperbolic 4-manifold M Abstract: In this talk, we will show how to compute the G-index of a spin closed hyperbolic 4-manifold M for a group G of symmetries of a spin structure on M. As an example, we will compute the G-index for the group G of symmetries of the fully symmetric spin structure on...

Topology and Group Theory Seminar: April 2, 2025
Mar. 8, 2025—Speaker: Talia Fernos (Vanderbilt) Title: Lattice envelopes and groups acting AU-acylindrically on products of hyperbolic spaces Abstract: In this joint work with Balasubramanya, we explore the capacity for a group acting AU-acylindrically on a finite product of delta-hyperbolic spaces to satisfy three properties introduced by Bader, Furman, and Sauer. When satisfied, these properties restrict the potential ambient group...

Colloquium – Talk by Steve Trettel: March 20, 2025
Mar. 6, 2025—March 26, 2025 (Wednesday), 4:10 pm Steve Trettel, University of San Francisco What do 3-manifolds Look Like? Thurston’s Geometrization Theorem, later proved by Perelman, describes 3-manifolds in terms of geometric building blocks. Each manifold decomposes into pieces modeled on one of just eight homogeneous 3-dimensional spaces, known as the Thurston geometries. In this talk, we...
