Late-time cosmological evolution of a general class of f(R, T) gravity with minimal curvature-matter coupling

Abstract

In this work, we study the late-time cosmological solutions of f(R,T)=g(R)+h(-T) models assuming that the conservation of the energy-momentum tensor (EMT) is violated. We perform our analysis through constructing an autonomous dynamical system for the equations of motion. We study the stability properties of solutions via considering linear perturbations about the related equilibrium points. These parameters which are constructed out of the functions g(R) and h(-T) play the main role in finding the late time behavior of the solutions.
