Standard monomials and Gröbner bases of positroid varieties
2024-04-03
Speaker: Daoji Huang (Univ. MInnesota, USA)
Influential work of Hodge from the 1940s led the way in using Gröbner bases to combinatorially study the Grassmannian. In this talk, we will follow Hodge's approach in order to investigate certain subvarieties called positroid varieties. Positroid varieties, introduced by Knutson-Lam-Speyer...
