Positroid varieties
nell'ambito della serie: SEMINARIO DI ALGEBRA E GEOMETRIA
algebra e geometria
Positroid varieties are intersections of cyclically rotated Schubert varieties in the Grassmannian, introduced in my work with Knutson and Speyer. I will discuss some aspects of these very nice spaces, including a recent computation of the cohomology of open positroid varieties in joint work with Galashin.
organizzato da: Jacopo Gandini, Luca Moci, Giovanni Mongardi nell'ambito del progetto TInGeCoRe "The Interplay of Geometry, Combinatorics and Representation Theory" (Bando Strutture 2020)
