摘要：General dynamics is an elegant description of interacting systems. The individual systems themselves are described by so called dispersion relations E(p)which formulates the connection of momentum pto energyE. Besides this relation there are others so-called generalized dispersions where e.g. charge Q and E or entropy Sand Eare connected (E(Q) and E(S)). Dispersions describe a system complete according to the related quantities. E(p) e.g. contains the kinetic energy Ekin, the momentum p and its potential (the velocity v), as well as the mass m of the system under consideration – nothing more to know about this system.

If two of those systems are in non-equilibrium to each other in respect to p, and are interacting, a process will start to reach equilibrium. There are situations where the exchange is strongest, are under resonant.

I will describe some generalized dispersions, the fundamental mathematical background, and give a few examples including the formation of structures.
