Riemannian and non-Riemannian extensions of geometrodynamics versus Einsteinian gravity
Abstract
Description
We analyze some extensions of General Relativity. Within the framework of modified gravity, the Newtonian limit of a class of gravitational actions is discussed on the basis of the corresponding scalar-tensor model. For a generalized asymmetric metric, autoparallel trajectories are defined under suitable conditions at first approximation order.
