WebAug 14, 2014 · 14. Since Grassmannian G r ( n, m) = S O ( n + m) / S O ( n) × S O ( m) is a homogeneous manifold, you can take any Riemannian metric, and average with S O ( n + m) -action. Then you show that an S O ( n + m) -invariant metric is unique up to a constant. This is easy, because the tangent space T V G r ( n, m) (tangent space to a plane V ⊂ W ... Webthe Grassmannian by G d;n. Since n-dimensional vector subspaces of knare the same as n n1-dimensional vector subspaces of P 1, we can also view the Grass-mannian as the set of d 1-dimensional planes in P(V). Our goal is to show that the Grassmannian G d;V is a projective variety, so let us begin by giving an embedding into some projective space.
