*Under weak field assumption: we can approximate Finslerianmetric as a perturbation of the FRW metric since in generalrelativity a weak vector field in a space (e.g a magnetic field)can be treated as a first order perturbation of the Riemannmetric tensor.We consider a convenient Finsler metric to approximate thegravitational theories. This metric is reffered as osculatingRiemannian metric( x)gˆ( x,Y )rµ!=µ!connected to the Riemanian one <strong>with</strong> the followingosculating affine connection A ! "µ(x)
