- TITLE
- Gromov-Hausdorff Distance and Quantified Borsuk-Ulam Theorems via Vietoris-Rips Complexes
- ABSTRACT
- The Gromov-Hausdorff distance is a fundamental metric defined on the space of isometry classes of compact metric spaces. In this presentation, we discuss recent developments in the computation of the Gromov-Hausdorff distance. In particular, we will focus on:
(1) The connection between Gromov-Hausdorff distance and quantitative versions of the Borsuk-Ulam Theorem; and
(2) How the Vietoris-Rips complex—a geometric simplicial complex—can strengthen the quantitative Borsuk-Ulam Theorem, ultimately achieving better lower bounds for the Gromov-Hausdorff distance.
Time permitting, we will discuss how the topology of Vietoris-Rips complexes contributes to the theoretical understanding of persistent homology, or by comparing the Gromov-Hausdorff distance with the Gromov-Wasserstein distance (which incorporates measure-theoretic "weights").
