| description | In this paper, we have studied an anisotropic Bianchi-I cosmological model in <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>f</mi><mo>(</mo><mi>R</mi><mo>,</mo><mi>T</mi><mo>)</mo></mrow></semantics></math></inline-formula> gravity. To obtain the exact solutions of the field equations, we have used the condition <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>σ</mi><mo>/</mo><mi>θ</mi></mrow></semantics></math></inline-formula> to be a function of the scale factor (<b>IJTP, 54, 2740-2757, 2015</b>). Our model possesses an initial singularity. It initially exhibits decelerating expansion and transits to accelerating expansion at late times. We have also discussed the physical and geometrical properties of the model. |
