Stability of Strange Quark Matter Cosmology in Modified Theory of Gravitation

Abstract

In this paper, we investigate the Bianchi type I metric of the Kasner form with strange quark matter coupled to the domain walls in the context of f(R,T) modified theory of gravitation. Three different functional forms of the function f(R,T) are considered. Stability of the investigated models is analyzed. It is found that the domain walls are stiff and the models represent the early stages of the evolution of the universe. It is also observed that the gravitation affects the behavior of the domain walls and the stability of the models.
