DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Matroids/30/
 ">Stellahedral geometry of matroids</a>\nby June Huh (Princeton University
 ) as part of Matroids - Combinatorics\, Algebra and Geometry Seminar\n\nLe
 cture held in Room 210 The Fields Institute.\n\nAbstract\nThe main result 
 is that valuative\, homological\, and numerical equivalence relations for 
 matroids coincide. The central construction is the "augmented tautological
  classes of matroids\," modeled after certain vector bundles on the stella
 hedral toric variety. Based on joint work with Chris Eur and Matt Larson\,
