Spinors,Calibrations and Grassmannians
Tsukuba Journal of Mathematics, 2003 A calibration on a Riemannian manifold \(M\) is a closed \(k\)-form \(\xi\) such that \(\xi_p(e_1\wedge\cdots\wedge e_k)\leq 1\) for every set of orthonormal vectors in \(T_pM\). The set of sets of orthonormal vectors for which we have equality is the contact set for \(\xi\); this set is required to be nonempty.

The affine Grassmannian as a presheaf quotient
Comptes Rendus. MathématiqueFor a reductive group $G$ over a ring $A$, its affine Grassmannian $\operatorname{Gr}_G$ plays important roles in a wide range of subjects and is typically defined as the étale sheafification of the presheaf quotient $LG/L^+G$ of the loop group $LG$ by ...

The positive orthogonal Grassmannian
Le MatematicheThe Plücker positive region $\mathrm{OGr}_+(k,2k)$ of the orthogonal Grassmannian emerged as the positive geometry behind the ABJM scattering amplitudes. In this paper we initiate the study of the positive orthogonal Grassmannian $\mathrm{OGr}_+(k,n)$ for general values of $k,n$.
