“…Therefore, the study of early anisotropic phases of the universe gains a lot of interest, and f (R, T ) gravity is no exception. Many authors have considered homogenous cosmological models in anisotropic and higher dimensional space-times as well (see for example [52,53,54,55,56,57,58,59,60,61] and references therein).…”

A plane symmetric Bianchi-I model is explored in f (R, T ) gravity, where R is the Ricci scalar and T is the trace of energy-momentum tensor. The solutions are obtained with the consideration of a specific Hubble parameter which yields a constant deceleration parameter. The various evolutionary phases are identified under the constraints obtained for physically viable cosmological scenarios. Although a single (primary) matter source is taken, due to the coupling between matter and f (R, T ) gravity, an additional matter source appears, which mimics a perfect fluid or exotic matter. The solutions are also extended to the case of a scalar field model. The kinematical behavior of the model remains independent of f (R, T ) gravity. The physical behavior of the effective matter also remains the same as in general relativity. It is found that f (R, T ) gravity can be a good alternative to the hypothetical candidates of dark energy to describe the present accelerating expansion of the universe.

“…The dynamical analysis of anisotropic spherically symmetric collapsing star has presented in this modified gravity [32]. This motivates the theorists to construct various models in different Bianchi space-times in different contexts [33,34,35,36,37,38]. In this paper, we consider LRS Bianchi-I space-time as our background metric and study the evolution of various cosmological parameters in f (R, T ) theory of gravity.…”

A spatially homogeneous anisotropic LRS Bianchi type-I cosmological model is studied in f (R, T ) gravity with a special form of Hubble's parameter, which leads to constant deceleration parameter. The parameters involved in the considered form of Hubble parameter can be tuned to match, our models with the ΛCDM model. With the present observed value of the deceleration parameter, we have discussed physical and kinematical properties of a specific model. Moreover, we have discussed the cosmological distances for our model.

“…To solve this problem, Harko et al suggested the f (R, T ) theory in 2011 [4]. This theory has recently been studied by many other scientists [5][6][7][8][9][10][11][12][13]. Myrzakulov and his colleagues investigated f (R, T ) gravitation theory for various matter contents and various space-time models [14][15][16].…”

Abstract:In this study, we have investigated homogeneous and anisotropic Marder space-time with bulk viscous string matter distribution in f (R, T ) gravity. For this aim we have used the anisotropy feature () of Marder space-time and a deceleration parameter in two different f (R, T ) models. We have obtained bulk viscous matter distribution solutions in f (R, T ) gravity. Finally, some kinematical and physical properties are discussed.
