Attend the seminar on 'Phylogenetics and Polytopes' organised by the Department of Mathematics at Syed Babar Ali School of Science and Engineering.
March 22, 2021
Motivated by questions from computational biology, we study a combinatorial classification of finite metric spaces by means of a new polyhedral invariant introduced by Vershik in 2010, known as the metric space's "fundamental polytopes''. These originate from the theory of optimal transport, in which they are often named after Wasserstein or Kantorovich-Rubinstein, and have recently found applications in a host of different contexts, from algebraic statistics to tropical geometry to the theory of reaction networks. Nevertheless, the most basic questions on their structure remain unanswered to date.
The session aims to illustrate and explain the basics of such polytopes.
