摘要：

The present work deals with cosmological solutions in f (R, T) gravity theory for perfect fluid with 1 constant equation of state (omega). For a viable cosmological solution omega is restricted to omega < 3 depending on the sign of an arbitrary constant one has two possible solutions: a finite universe model and an ever expanding model of the universe. Field theoretic description of the model and possibility of a ghost scalar field has been studied. Also, an equivalence with modified Chaplygin gas has been shown. Finally, from the observational data it has been concluded that this model represents an evolution of the universe from matter dominated phase to present accelerating phase.(c) 2022 Published by Elsevier B.V. .
