Abstract
BAISHYA, KANAK ΚΑΝTΙ and MUKHARJEE, AJOY. On the space-time admitting some geometric structures on energy-momentum tensors. Rev.colomb.mat. [online]. 2017, vol.51, n.2, pp.259-269. ISSN 0034-7426.
This paper presents a study of a general relativistic perfect fluid space-time admitting various types of curvature restrictions on energy-momentum tensors and brings out the conditions for which fluids of the space-time are sometimes phantom barrier and some other times quintessence barrier. The existence of a space-time where fluids behave as phantom barrier is ensured by an example.
Keywords : General relativistic perfect fluid space-time; Einstein's field equation; energy-momentum tensor; semi-symmetric energy-momentum tensor.
