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. This is equivalent to identifying it with V … See more The quickest way of giving the Grassmannian a geometric structure is to express it as a homogeneous space. First, recall that the general linear group $${\displaystyle \mathrm {GL} (V)}$$ acts transitively on the $${\displaystyle r}$$-dimensional … See more For k = 1, the Grassmannian Gr(1, n) is the space of lines through the origin in n-space, so it is the same as the projective space of … See more Let V be an n-dimensional vector space over a field K.
