Descripción
This article presents a statistical-mechanical treatment of a
relationship (the force equation) between the gravitational potential
for two particles and the correlation functions in a relaxed
distribution of particles with different masses. This relationship is
used in the case of galaxies interacting through a Newtonian potential
in a Universe in expansion, i.e. the large-scale distribution of
galaxies. By applying this equation and from the observed two-point
correlation function for galaxies as a -1.8 exponent power law, I derive
the approximate dependence of a mass-mass correlation function as a -2.8
exponent power law, i.e. I infer that mass is more correlated than
galaxies at short distances, when the distribution is considered as
relaxed.
