In differential geometry, Schur's Lemma usually refers to the result that if the sectional curvature of a
Riemannian manifold does not depend on the choice of 2-plane in any tangent space, then it also does not depend on the point in the manifold, i.e., the manifold has constant curvature. Shouldn't
