Taking the amplituhedron to the limit
The limit amplituhedron for m=2 and any k is a positive geometry whose algebraic boundary is the union of the Chow hypersurface of a rational normal curve and the Chow hypersurface of a secant line.

Points on Rational Normal Curves and the ABCT Variety
The paper derives a recursive formula for the cohomology class of the ABCT variety V(3,n) inside the Grassmannian G(3,n), using a determinantal realization and Porteous' formula, and matches special coefficients to Eu...
