In this chapter, we first introduce the Grassmannian variety and its Schubert varieties. We then present the details on the standard monomial theory (cf. Hodge [30, 31]); we also present a proof of “vanishing theorems.” Differential geometry of Grassmannian embeddings of based ... and the (linearly) divergent expression corresponding to the Ricci curvature of the restricted Grassmannian after proving that the latter manifold is an isotropy irreducible Hermitian symmetric space. Using the Gauss equation of the embedding of a based loop group into the restricted Grassmannian we show that On the Geometry of Infinite Dimensional Grassmannian ...

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. The Grassmannian Variety Geometric and Representation ... This book gives a comprehensive treatment of the Grassmannian varieties and their Schubert subvarieties, focusing on the geometric and representation theoretic aspects of Grassmannian varieties. Research of Grassmannian varieties is centered at the crossroads of commutative algebra, algebraic geometry, representation theory, and combinatorics. | Nima ... 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. by Nima ... Download full list. ... The book begins by deriving connections between scattering amplitudes and Grassmannian geometry from first principles before introducing novel physical and mathematical ideas in a systematic manner accessible to both physicists and mathematicians. The principle players in this process are on shell functions which are ... Title On the geometry of Grassmannian equivalent connections Next we study the geometry of n Grassmannian equivalent connections, that is linear connections without torsion admitting the same equation of n dimensional totally geodesic submanifolds. We define the n Grassmannian structure as the equivalence class of such connections, recovering for n=1 the case of theory of projectively equivalent connections.

For `hyperbolic grassmannian geometries, we prove some facts (for instance, that the Plucker map is a minimal isometric embedding) that were previously known in the `elliptic case. ebook by ...

In , , , the authors investigated the birational geometry of compactified moduli spaces of rational curves of degree ≤3 in projective spaces and homogeneous varieties. The purpose of this paper is to investigate the geometry of moduli spaces of rational curves of degree ≤3 in linear sections of Grassmannian G r (2, 5). Download Free.
