  Based on the concept of material event as an elementary material source that
is concentrated on metric sphere of zero radius --- light-cone of Minkowski
space-time, we deduce the analog of Coulomb's law for hyperbolic space-time
field universally acting between the events of space-time. Collective field
that enables interaction of world lines of a pair of particles at rest contains
a standard 3-dimensional Coulomb's part and logarithmic addendum. We've found
that the Coulomb's part depends on a fine balance between causal and geometric
space-time characteristics (the two regularizations concordance).
