On a 4-dimensional manifold $$M$$, the authors study the effects of two types of deformations of the pseudo-Riemannian metric $$\gamma_{ij}$$ with connection $$N$$. First, a small Finslerian perturbation and then a conformal deformation are considered. For each of these deformed models, the arising $$(h, v)$$ metric structures on $$TM$$ are given. The Einstein equations, as well as the equations of the stationary curves and their deviations in these models, are obtained.
