at a point

A submanifold of a smooth manifold (Riemannian or with an affine connection) such that the geodesic lines (cf. Geodesic line) of that are tangent to at have a contact of at least the second order with . This requirement is fulfilled at all points if any geodesic in is also a geodesic in . Such geodesic manifolds are called totally geodesic manifolds.


Comments

Also called geodesic submanifold and totally geodesic submanifold, respectively.
