ABSTRACT. As it has been recently demonstrated,the mathematical model with the hyperbolic space(or, in other words, with the negative spatial curvature)is the most appropriate one for describing the inhomogeneous Universe at late stages of its evolution in the framework of the theory of scalar perturbations. In this model we develop a dynamic approach and investigate nonrelativistic motion of two, three and even more cosmic bodies against the cosmological background, perturbed locally by density inhomogeneities (namely, galaxies).
