DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Matroids/35/
 ">Generalized Permutahedra and Positive Flag Dressians</a>\nby Michael Jos
 wig (MPI MiS Leipzig) as part of Matroids - Combinatorics\, Algebra and Ge
 ometry Seminar\n\nLecture held in Room 210 The Fields Institute.\n\nAbstra
 ct\nWe study valuated matroids\, their tropical incidence relations\, flag
  matroids and total positivity. This leads to a characterization of subdiv
 isions of regular permutahedra into generalized permutahedra. Further\, we
  get a characterization of those subdivisions arising from positive valuat
 ed flag matroids.\n
