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 ... birth dates zodiac signs
