Geometry & Topology
Title: Persistent Homology Learning Seminar
Speaker: Rafal Komendarczyk - Tulane University
Abstract: The Persistent Homology Learning Seminar (MATH-7760-02) resumes this week and meets weekly through the fall, Thursdays 12:30-1:30 PM in Gibson Hall GI-308.
Please note the room: this is not where we met on August 27.
The seminar is organized around one question: when are two metric spaces close, and which topological invariants respect that closeness? We take the
Gromov-Hausdorff distance as the measure of similarity between metric spaces and work toward the stability theorem
d_B(B(X), B(Y)) <= 2 d_GH(X, Y), which says that the persistence barcode is a Lipschitz invariant of the data.
All interested are welcome to attend. No prior exposure to persistent homology is assumed.
Location: Gibson Hall GI-308
Time: 12:30 PM
