On Pseudo-Petrov Symmetric Riemannian Manifolds
Autor: Sanjib Kumar Jana, Fusun Nurcan, Amit Kumar Debnath, Joydeep Sengupta
Publikováno v: Advances in Mathematical Physics, Vol 2016 (2016)
The present paper deals with pseudo-Petrov symmetric Riemannian manifolds whose space-matter tensor satisfies a special condition. Firstly, basic results of pseudo-Petrov symmetric Riemannian manifolds are obtained. Then, pseudo-Petrov symmetric mani

On quasi-Einstein spacetime with space-matter tensor
Autor: Sanjib Kumar Jana, Absos Ali Shaikh
Publikováno v: Lobachevskii Journal of Mathematics. 33:255-261
The object of the present paper is to discuss quasi-Einstein spacetime with spacematter tensor and study some of its geometric and global properties. Also the existence of such a spacetime is ensured by a non-trivial example.

On weakly cyclic Ricci symmetric manifolds
Autor: Absos Ali Shaikh, Sanjib Kumar Jana
Publikováno v: Annales Polonici Mathematici. 89:273-288
We introduce a type of non-flat Riemannian manifolds called weakly cyclic Ricci symmetric manifolds and study their geometric properties. The existence of such manifolds is shown by several non-trivial examples.
