| Abstract: | In this paper we derive a wave equation based on a cosmological model of the universe expansion in the four-dimensional space-velocity.
An analytical solution of this equation is obtained using Nikiforov-Uvarov mathematical method. In this procedure we use the
solutions of the Einstein gravitational field equations for the perfect fluid energy-momentum tensor. |
