On $(N (k), ξ)$ -semi-Riemannian manifolds: Pseudosymmetries

Mukut Mani Tripathi, Punam Gupta

Definition of $(T_{a}, T_{b})$ -pseudosymmetric semi-Riemannian manifold is given. $(T_{a}, T_{b})$ -pseudosy mmetric $(N (k), ξ)$ -semi-Riemannian manifolds a…

Index of quasi-conformally symmetric semi-Riemannian manifolds

Mukut Mani Tripathi, Punam Gupta, Jeong-Sik Kim

We find the index of $\nabla$ -quasi-conformally symmetric and $\nabla$ -concircularly symmetric semi-Riemannian manifolds, where $\nabla$ is metr…

On $(N (k), ξ)$ -semi-Riemannian manifolds: Semisymmetries

Mukut Mani Tripathi, Punam Gupta

$(N (k), ξ)$ -semi-Riemannian manifolds are defined. Examples and properties of $(N (k), ξ)$ -semi-Riemannian manifolds are given. Some relations involving $T_{a}$ -curvature tenso…
