On equivalency of various geometric structures
Absos Ali Shaikh,Haradhan Kundu +1 more
TL;DR: A tensor is presented by combining Riemann–Christoffel curvature Tensor, Ricci tensor, the metric tensor and scalar curvature which describe various curvature tensors as its particular cases and is proved to have equivalency of different geometric structures.

On Riemann and Weyl Compatible Tensors
Ryszard Deszcz,Małgorzata Głogowska,Jan Jełowicki,Miroslava Petrovic-Torgasev,Georges Zafindratafa +4 more
TL;DR: In this paper, the authors investigated semi-Riemannian manifolds satisfying some curva- ture conditions and showed that these conditions are strongly related to pseudosymmetry.

Natural Intrinsic Geometrical Symmetries
TL;DR: In this article, a proposal is made for what could well be the most natural symmetrical Rie-mannian spaces which are homogeneous but not isotropic, i.e., spaces which satisfy the axiom of free mobility.
