The two lives of the Grassmannian
The real Grassmannian is both a projective variety (via Plücker coordinates) and an affine variety (via orthogonal projections). We connect these two representations, and we develop the commutative algebra of the latter variety.

ABJM amplitudes and the positive orthogonal Grassmannian
, 2018 A remarkable connection between perturbative scattering amplitudes of four dimensional planar SYM, and the stratification of the positive Grassmannian, was revealed in the seminal work of Arkani-Hamed et al.

Families of lines in Fano varieties complete intersection in a Grassmannian
Le Matematiche, 2002 In this paper we determine all Fano varieties which are complete intersections of hypersurfaces in a Grassmannian. Then, in the case Fano's conjecture is satisfied, we give a formula in order to compute the dimension of the Hilbert scheme that ...

Homology of bi-Grassmannian complexes.
, 1997 This paper is devoted to the proof of this assertion with rational coefficients. Also we prove a similar formula for truncated complex consisting only of the several bottom rows of bi-Grassmannian complex up to the n\Gammath one. This formula is valid in
