Description: According to the gravitoelectromagnetic description of the gravitational phenomena, the Maxwell-Heaviside equations (GEM equations) govern the gravitational field. In this article these equations are mathematically deduced from the kinematics of the EinformatonsE, that E" according to the Etheory of informatonsE - are the constituent elements of that field. It is also shown that the GEM equations are mathematically consistent and that they imply the existence of gravitational waves.
