Killing tensors on products of Riemannian manifolds with one compact factor are reducible sums of factor tensors.
GTSA-PCA replaces global PCA covariance with curvature-weighted local operators and a geodesic alignment step to produce geometry-aware embeddings that improve on standard PCA and UMAP in small-sample high-curvature settings.
Constructs a Riemannian metric on the 2-torus such that its universal cover does not admit global Riemann normal coordinates.
