WebGrassmannian and flag varieties, which stem from linear algebra, are significant study objects in the interplay of algebraic geometry, representation theory, and combinatorics. The symplectic Grassmannian and flag variety attracted a lot of in-terest from researchers as well.

WebThe Grassmann Manifold 1. For vector spaces V and W denote by L(V;W) the vector space of linear maps from V to W.Thus L(Rk;Rn) may be identified with the space Rk£n of k £ n matrices. An injective linear map u: Rk!V is called a k-frame in V. The set GFk;n = fu 2 L(Rk;Rn) : rank(u) = kg of k-frames in Rn is called the Stiefel manifold.

In mathematics, the Grassmannian Gr(k, V) is a space that parameterizes 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. In ge…
