We construct the kinetic potentials that appear on the generalized Clebsch representation for the velocity field of a perfect fluid with a politropic state equation that describes the matter distribution in a Newtonian homogeneous isotropic universe. We also specify the constants of motion with respect to the HS group.

Abstract
We construct the kinetic potentials that appear on the generalized Clebsch representation for the velocity field of a perfect fluid with a politropic state equation that describes the matter distribution in a Newtonian homogeneous isotropic universe. We also specify the constants of motion with respect to the HS group.| File | Dimensione | Formato | |
