Compact orientable submanifold of codimension $2$ in an odd dimensional sphere
Compact orientable submanifold of codimension $2$ in an odd dimensional sphere
has been proved by W. Suss [6]. Recently Y. Katsurada [1], [2] and K. Yano[9] have generalized the above theorem to an ra-dimensional hypersurface inan Einstein space admitting one-parameter groups of conformal transformationsor of homothetic transformations.Thus we may expect an analogous theorem for a submanifold of co-dimension greater than 1 …
