A mathematical method for irregular hamiltonian systems
Qiuping A. Wang, Wei Li
We present certain mathematical aspects of an information method which was formulated in an attempt to investigate diffusion phenomena. We imagine a regular dynamical hamiltonian s…
Fourier's law and maximum path information
Q. A. Wang
By using a path information defined for the measure of the uncertainty of instable dynamics, a theoretical derivation of Fourier's law of heat conduction is given on the basis of m…
Diffusion laws, information and action principle
Qiuping A. Wang
This is an attempt to address diffusion phenomena from the point of view of information theory. We imagine a regular hamiltonian system under the random perturbation of thermal (mo…
Maximum entropy change and least action principle for nonequilibrium systems
Qiuping A. Wang
A path information is defined in connection with different possible paths of irregular dynamic systems moving in its phase space between two points. On the basis of the assumption…
