Elliptic solutions of generalized Brans–Dicke gravity with a non-universal coupling
Elliptic solutions of generalized Brans–Dicke gravity with a non-universal coupling
We study a model of the generalized Brans-Dicke gravity presented in both the Jordan and in the Einstein frames, which are conformally related. We show that the scalar field equations in the Einstein frame are reduced to the geodesics equations on the target space of the nonlinear sigma-model. The analytical …
