The statistics of the gravitational field arising from an inhomogenous system of particles
A. Del Popolo, M. Gambera, x
In this paper we extend Chandrasekhar and von Neumann's analysis of the statistics of the gravitational field to systems in which particles (e.g. stars, galaxies) are not homogeneo…
