Abstract: We study contact of higher order of Riemannian manifolds (or metrics). The main results concern "contact homogeneous Riemannian manifolds" (of arbitrary order) and envelopes of Riemannian metrics (of the first and second order).
Keywords: Riemannian manifold, contact of Riemannian metrics, envelopes of Riemannian metrics, curvature homogeneous space, semi-symmetric space
Classification (MSC91): 53C20, 53C30, 53C35, 53B20.
