The Chow-Lam Form for Subvarieties of Grassmannian

Explore a 29-minute conference talk from the Amplituhedra, Cluster Algebras, and Positive Geometry Conference where UC Berkeley researcher Lizzie Pratt delves into the mathematical concept of the Chow-Lam form for subvarieties of a Grassmannian. Learn how the classical Chow form's ability to encode projective varieties through single equations extends to new mathematical territories, and discover how evaluating the Chow-Lam form at twistor coordinates yields universal projection formulas - a technique pioneered by Thomas Lam in studying amplituhedra and positroid varieties. Gain insights into this collaborative research conducted with Bernd Sturmfels, presented at Harvard CMSA's mathematics conference.
