MACPHERSON Institut des Hautes Etudes Scientifliques, 35 route de Chartres, 91440 Bures sur Yvette, France In this paper we introduce some polyhedra in Grassman manifolds which we call Grassmannian simplices.

First, the BCFW contour in terms of (reduced) Grassmannian geometry representatives is dissected into a triangle shape sum, as only a small fraction of the sum needs to be explicitly identified. The Grassmannian geometry of spectra ScienceDirect The Grassmannian geometry of spectra 73 We have the canonical map Sk(9ll) "ll sending a point to itself a set K is in Gk(W) if and only if the image of the restriction to K of Sk (W) lies in W. But the restriction to K is a bundle with compact base and fiber, and therefore compact total space..

Abstract This paper contains a thorough introduction to the basic geometric properties of the manifold of Lagrangian subspaces of a linear symplectic space, known as the Lagrangian Grassmannian. It also reviews the important relationship between hypersurfaces in the Lagrangian Grassmannian and second order PDEs. Amazon.com ... This is an essential introduction to the geometry and combinatorics of the positroid stratification of the Grassmannian and an ideal text for advanced students and researchers working in the areas of field theory, high energy physics, and the broader fields of mathematical physics. Grassmannian Wikipedia In mathematics, the Grassmannian Gr(k, V) is a space which parametrizes all k dimensional linear subspaces of the n dimensional vector space V.For example, the Grassmannian Gr(1, V) is the space of lines through the origin in V, so it is the same as the projective space of one dimension lower than V.. When V is a real or complex vector space, Grassmannians are compact smooth manifolds. On the Geometry of Infinite Dimensional Grassmannian ...

Outlining a revolutionary reformulation of the foundations of perturbative quantum field theory, this book is a self contained and authoritative analysis of the application of this new formulation to the case of planar, maximally supersymmetric Yang Mills theory. Positivity, Grassmannian geometry and simplex like ... A bstract. This article revisits and elaborates the significant role of positive geometry of momentum twistor Grassmannian for planar \( \mathcal{N}=4 \) SYM scattering amplitudes. First we establish the fundamentals of positive Grassmannian geometry for tree amplitudes, including the ubiquitous Plücker coordinates and the representation of reduced Grassmannian geometry. | Nima ...
