weakly symmetric Riemannian manifold; weakly projective symmetric Riemannian manifolds
The authors introduce the notions of weakly symmetric and weakly projective symmetric Riemannian manifolds generalizing the concepts of pseudo-symmetric and pseudo-projective symmetric Riemannian manifolds due to M. C. Chaki and S. K. Saha. The properties of these notions and special cases are investigated.
