Show List of Speakers


This workshop will concentrate on tropical methods in Combinatorics and Algebra. Some of the topics we expect to explore are:

  • Tropical ideas in combinatorial linear algebra, such as tropical convexity, tropical linear spaces and oriented matroids, tropical matrix algebra and its applications.
  • Tropical methods in combinatorial representation theory, including both discovery of new formulas and improved understanding of old ones.
  • Computational issues, including both how to compute tropical objects and how to use tropical tools in other computational settings.
  • Applications of tropical methods in algebraic statistics.
