摘要：
A spatially homogeneous and anisotropic Bianchi type-VI cosmological model in the framework of f(Q,T) gravity has been studied by considering three different functional forms of f(Q,T) i.e. f(Q,T) = aQ + bT, f(Q,T) = aQ(k) + bT and f(Q,T) = -aQ - bT(2). The field equation of f(Q,T) gravity has been solved with the help of the Bianchi type-VI line element. The cosmological parameters of the models are evaluated, and the dynamical aspects of the model have been discussed. The result agrees with the observations of accelerated expansion of the universe.
