Estimating the nonextensivity of systems from experimental data: a nonlinear diffusion equation approach

Frank, T.D.; Friedrich, R. - In: Physica A: Statistical Mechanics and its Applications 347 (2005) C, pp. 65-76

We consider nonextensive systems that are related to the nonextensive entropy proposed by Tsallis and can be described by means of the nonlinear porous medium equation and the nonlinear Fokker–Planck equation proposed by Plastino and Plastino. We show how to determine the degree of...
