摘要: We generalize the scalar tensor bigravity models to non-minimal kinetic coupling with two fields whose terms are non-minimally coupled Einstein tensors constructed by metrics. show that a broad class of expanding universes can be explained some solutions this model. Then, we study stability issue means imposing homogeneous perturbation on equations motion and extract stable solutions.
