Black hole motion in entropic reformulation of general relativity

Abstract
We consider a system of black holes
-- a simplest substitute of a system of point particles
in the mechanics of general relativity --
and try to describe their motion with the help of
entropic action: a sum of the areas of black hole
horizons.
We demonstrate that such description is indeed consistent
with the Newton's laws of motion and gravity,
modulo numerical coefficients, which coincide but seem
different from unity.
Since a large part of the modern discussion of
entropic reformulation of general relativity is actually
based on dimensional considerations,
for making a next step it is crucially important to
modify the argument, so that these dimensionless
parameters acquire correct values.
