Geometry & Geometric Analysis Seminar
Main Content
The Geometry and Geometric Analysis (GAGA) Seminar is an opportunity for geometers, topologists, and others from TCU and other campuses to learn about new topics of mutual interest. GAGA meets most weeks during the school year. You can find notes from past talks at the GAGA Note Repository, located in a secure off-campus location.
The Fall 2026 GaGA seminar is Fridays at 1 pm in TUC 352 on TCU campus, and also the seminar will be available on Zoom. Contact Ken Richardson with any questions or issues with the link.
The first talk: Friday, September 4, 1 pm
Speaker: Jack Mealy (Austin College)
Title: Closed Geodesics in StairCase Metric (SCM) manifolds
Abstract: After an introduction to the category, StairCase Metric (SCM) Geometry, we focus on
defining various SCM manifolds with non-trivial topology. In these we can find exactly,
then categorize, the geodesics. In our last example, a reasonably natural space-time
SCM manifold is defined and studied; then various properties of subcategories of the
time-like geodesics are identified.
