Relativistic fluid dynamics in a non-vacuum régime

The author obtains the fundamental aspects of relativistic fluid dynamics in a non-vacuum régime. As the basic model is taken the special theory of relativity in the form proposed by Einstein (1907), Fock (1955) and others. The model takes account of the influence of the gravitational field upon the velocity of the propagation of light.The research was sponsored by the Research Department, Michigan State University, under the directorship of Mr. John Hoffman, and this is gratefully acknowledged.
