Özet
In the context of f (R, T) modified gravity theory, we consider a homogeneous and anisotropic Bianchi type-I cosmological model which relies on the condition of a constant jerk parameter, j = 1, corresponding to a flat Lambda CDM model. Under this condition, we obtain two different solutions, one is power-law and the other one is exponential. The power-law solution gives a decelerating model, while the exponential one yields an accelerating cosmology. We discuss the physical and geometric properties of both models, validity of the solutions, and the significance of modified f (R, T) gravity for the models.
