摘要

通过考虑H定理，我们研究了由两个不同子系统组成的系统在不同的非线性福克-普朗克方程下的动力学。当这些方程中的非线性相同时，我们使用H定理来获得建立系统相互作用的适当依赖性所需的条件，该依赖性符合热力学定律。在这个框架中，我们还考虑了每个子系统的不同动力学方面，并研究了复合系统熵的可能表达式。

Nonlinear Fokker-Planck Equations, H-Theorem and Generalized Entropy of a Composed System.

We investigate the dynamics of a system composed of two different subsystems when subjected to different nonlinear Fokker–Planck equations by considering the H–theorem. We use the H–theorem to obtain the conditions required to establish a suitable dependence for the system’s interaction that agrees with the thermodynamics law when the nonlinearity in these equations is the same. In this framework, we also consider different dynamical aspects of each subsystem and investigate a possible expression for the entropy of the composite system.

期刊介绍： Entropy (ISSN 1099-4300), an international and interdisciplinary journal of entropy and information studies, publishes reviews, regular research papers and short notes. Our aim is to encourage scientists to publish as much as possible their theoretical and experimental details. There is no restriction on the length of the papers. If there are computation and the experiment, the details must be provided so that the results can be reproduced.
