Geometry of grassmannian

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 … See more By giving a collection of subspaces of some vector space a topological structure, it is possible to talk about a continuous choice of subspace or open and closed collections of subspaces; by giving them the structure of a See more To endow the Grassmannian Grk(V) with the structure of a differentiable manifold, choose a basis for V.

Grassmanians are symmetric spaces, and symmetric spaces are "geodesic orbit spaces", that is, their geodesics are orbits of their group of isometries. Your Grassmanians, in particular, are of the form S U ( p + q) / S U ( p) × S U ( q). If g is the Lie algebra of the big group and h ⊆ g the Lie algebra of the subgroup, then there ...
