DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Knotsandtopo
 logy/166/">Gromov-Hausdorff distances\, Borsuk-Ulam theorems\, and Vietori
 s-Rips complexes</a>\nby Henry Adams as part of Knots and representation t
 heory\n\n\nAbstract\nThe Gromov-Hausdorff distance is a notion of dissimil
 arity between two datasets or between two metric spaces. It is an importan
 t tool in geometry\, but notoriously difficult to compute. I will show how
  to provide new lower bounds on the Gromov-Hausdorff distance between unit
  spheres of different dimensions by combining Borsuk-Ulam theorems with Vi
 etoris-Rips complexes. This joint work with 15 coauthors is available at h
 ttps://arxiv.org/abs/2301.00246. Many questions remain open!\n
