Cosmology from f(R,T) Theory in a Variant Speed of Light Scenario

  • P. H. R. S. Moraes
Article

Abstract

In this work I present a generalization of f(R, T) gravity, by allowing the speed of light to vary. Cosmological solutions are presented for matter and radiation-dominated universes, the former allowing the universe expansion to accelerate while the latter contemplating a possible alternative to inflationary scenario. Remarkably, standard gravity is always retrieved for a special case of f(R, T).
