This article will show how by adding a third "hidden" variable to the two parameters in Lotka's law, this law becomes equivalent, in a strict logical sense, with Mandelbrot's. Similarly, Lotka's inverse square law becomes equivalent with Leimkuhler's. We will also show how Pareto's law fits into this framework.

This work deals with the relation between the numerical solutions of hyperbolic systems of conservation laws and the associated entropy evolution. An analysis of the continuum problem by means of variational calculus clearly emphasizes the consequences of the adopted reconstruction procedure on the
