On the boltzmann equation
WebApart from the smoothing parameter + these equations are the same as N-body equations of motion (9.2). Ho we ver,itÕs important to remember that the bodies are tracers of the phase-space distrib ution, and not to be identi Þ ed with indi vidual stars. The smoothing procedure incorporated into these equations is commonly called ÔPlummer soft- WebBoltzmann Equation. Since the Boltzmann equation is quadratic it involves only binary collision therefore an important step is to prove that other events can be excluded and this is a direct consequence of the following theorem (cf. [43, p. 65]): “The set of points that are led into a multiple collision under forward or backward evolution of the dynamical system and …
