for all vector fields X, Y where S is the Ricci tensor of the type (0, 2), r is the scalar curvature, k is the gravitational constant and T is the energy momentum tensor of type (0, 2).
The energy momentum tensor T is said to describe a perfect fluid [2] if
In a Lorentzian para- Sasakian type spacetime by considering the characteristic vector field [xi] as the flow vector field of the fluid, the energy momentum tensor takes the form
In the general theory of relativity, energy momentum tensor plays an important role and the condition on energy momentum tensor for a perfect fluid space time changes the nature of space time (5).
We know an energy momentum tensor T will be covariant recurrent (6) if
So we like to define generalized covariant recurrent energy momentum tensor as follows:
An energy momentum tensor T is said to be generalized covariant recurrent if
Generalized recurrent energy momentum tensor in a general relativistic space time
where k is the Einstein's gravitational constant, T is the energy momentum tensor of type (0,2) given by
Although there are physical arguments for equating the Einstein tensor to the energy momentum tensor ([G.
The energy momentum tensor in this symmetry (and this particular case) is:
We note that 3S may be taken as the intrinsic angular momentum tensor for microscopic physical objects which may be seen as the points in the space-time continuum itself.
