Semiconformal symmetry- A new symmetry of the spacetime manifold of the general relativity
Musavvir Ali, Naeem Ahmad Pundeer, Zafar Ahsan
In this paper we have introduced a new symmetry property of spacetime which is named as semiconformal curvature collineation, and its relationship with other known symmetry propert…
Curvature properties of a special type of pure radiation metrics
Absos Ali Shaikh, Haradhan Kundu, Musavvir Ali +1
A spacetime denotes a pure radiation field if its energy momentum tensor represents a situation in which all the energy is transported in one direction with the speed of light. In…
Curvature properties of Robinson-Trautman metric
Absos Ali Shaikh, Musavvir Ali, Zafar Ahsan
The curvature properties of Robinson-Trautman metric have been investigated. It is shown that Robinson-Trautman metric admits several kinds of pseudosymmetric type structures such…
Curvature Tensor for the Spacetime of General Relativity
Zafar Ahsan, Musavvir Ali
In the differential geometry of certain F-structures, the role of W-curvature tensor is very well known. A detailed study of this tensor has been made on the spacetime of general r…
Classification of totally umbilical slant submanifolds of a Kenmotsu manifold
Siraj Uddin, Zafar Ahsan, A. H. Yaakub
The purpose of this paper is to classify totally umbilical slant submanifolds of a Kenmotsu manifold. We prove that a totally umbilical slant submanifold of a Kenmotsu manifold…
