Submanifolds,he ambient manifold .to simplify the notation because it may cause no confusion. Let T(M) and T(M). denote the tangent and normal bundle of M respectively. The metric g and the connection .on .lead to invariant inner products and the connections on T(M) and T(M). We will define a connection on M explicitely.

Submanifolds, of covariant differentiation in .and by g the Riemannian metric tensor field in .. Since the discussion is local, we may assume, if we want, that M is imbedded in .. The submanifold M is also a Riemannian manifold with Riemannian metric h given by h(X,Y) = g(X,Y) for any vector fields X and Y on M.
