DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TGiZ/19/">Tr
 opical geometry of phylogenetic tree spaces</a>\nby Anthea Monod (Imperial
  College London) as part of Tropical Geometry in Frankfurt/Zoom TGiF/Z\n\n
 \nAbstract\nThe Billera-Holmes-Vogtmann (BHV) space is a well-studied modu
 li space of phylogenetic trees that appears in many scientific disciplines
 \, including computational biology\, computer vision\, combinatorics\, and
  category theory. Speyer and Sturmfels identify a homeomorphism between BH
 V space and a version of the Grassmannian using tropical geometry\, endowi
 ng the space of phylogenetic trees with a tropical structure\, which turns
  out to be advantageous for computational studies. In this talk\, I will p
 resent the coincidence between BHV space and the tropical Grassmannian. I 
 will then give an overview of some recent work I have done that studies th
 e tropical Grassmannian as a metric space and the practical implications o
 f these results on probabilistic and statistical studies on real datasets 
 of phylogenetic trees.\n
