Assume that in a Lorentzian frame is given a relativistically admissible
trajectory of a point mass. An event in such a frame can be described by four
coordinates, first three representing the position and the last one the time of
the event. Let G denote the set of all events that do not lie on the
trajectory.

One of the highlight of this note is that the author presents the
relativistic gravity field that Einstein was looking for. The field is a
byproduct of the matter in motion. This field can include both the discrete and
continuous components. In free space the waves produced in this field propagate
with velocity of light.

Another highlight is the proof of amended Feynman's formulas for
electromagnetic potentials. This makes the formulas mathematically complete and
precise.

In a fixed Lorentzian frame given is a trajectory $r_2(t,r_0)$ of moving
plasma such that each line $t\mapsto r_2(t,r_0)$ of flow has derivatives with
respect to $t$ of order 3. The parameter $r_0$ represents the position of the
plasma at some initial time $t_0$ and changes in a compact set $F.$ It is
assumed that the map $(t,r_0)\mapsto r_2(t,r_0)$ is continuous and for fixed
$t$ the map $r_0\mapsto r_2(t,r_0)$ is one-to-one on $F.$
