Thus motivated sufficiently, we study Ricci curvature and scalar curvature of submanifolds in contact metric manifolds.

To be more specific, the results obtained (in this paper) for submanifolds of ([kappa], [mu])-space forms generalize the corresponding results for submanifolds of Sasakian space forms and at the same time several results and examples.

An immersed submanifold of a manifold M is the image S of an immersion map f: N → M; in general this image will not be a submanifold as a subset, and an immersion map need not even be injective (one-to-one) – it can have self-intersections.

More narrowly, one can require that the map f: N → M be an injection (one-to-one), in which we call it an injective immersion, and.
