Matroids and Toric varieties   (Teddy Gonzales, Oct.2, 2024) at 2PM in H705
I will discuss one "geometric model" of matroids which arises from viewing their representations as points on the Grassmannian and taking torus orbit closures due to Gelfand, Goresky, MacPherson, and Serganova. If time permits, I will describe how this relates to Berget, Eur, Spink, and Tseng's "tautological classes" of matroids which are certain equivariant classes on the permutohedral variety.
