EQUIVARIANT $K$ -THEORY OF GRASSMANNIANS by OLIVER PECHENIK, ALEXANDER YONG

“…We address a unification of the Schubert calculus problems solved by Buch [A Littlewood–Richardson rule for the $K$ -theory of Grassmannians, Acta Math. 189 (2002), 37–78] and Knutson and Tao [Puzzles and (equivariant) cohomology of Grassmannians, Duke Math. …”

Non-planar BCFW Grassmannian geometries by Shruti Paranjape, Jaroslav Trnka, Minshan Zheng

“…We show that these terms can be interpreted as dlog forms on the non-planar Grassmannian geometries, generalizing the cells of the positive Grassmannian G +(k, n) to a larger class of objects which live in G(k, n). …”

Arrangements of equal minors in the positive Grassmannian by Farber, Miriam, Postnikov, Alexander

“…Weakly separated sets, originally introduced by Leclerc and Zelevinsky, are closely related to the positive Grassmannian and the associated cluster algebra. However, we also construct examples of arrangements of smallest minors which are not weakly separated using chain reactions of mutations of plabic graphs. …”

Twistor-Strings, Grassmannians and Leading Singularities by Bullimore, M, Mason, L, Skinner, D

“…We go on to show that the genus g twistor-string moduli space for g-loop N^{k-2}MHV amplitudes may be mapped into the Grassmannian G(k,n). Restricting to a leading singularity, the image of this map is a 2(n-2)-dimensional subcycle of G(k,n) of exactly the type found from the Grassmannian residue formula of Arkani-Hamed, Cachazo, Cheung and Kaplan. …”
