Attempt to construct a general covariant theory of a scalar gravitational field

An attempt is made in this paper to construct a scalar theory of gravitation which is based on the main postulates of the general theory of relativity (GTR), i.e., on the principle of the equivalence of inertial and gravitational mass and on the principle of general covariance of the theory.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 75–79, April, 1984.
