Generalized Klimontovich theory for fluctuations and correlations in plasmas

In order to deal with a non-ideal plasma a method is developed that gives a microscopic hierarchy of equations for the fluctuation in density of a classical plasma, existing of pointlike particles. Starting from the evolution equations of a Fourier-transformed one-particle distribution function, expressions for every correlation function can be found in a straightforward way. Results like the Landau- and the Lenard-Balescu collision integral and the time-dependent correlation functions of Rostoker are recovered when we cut off this hierarchy in the lowest significant order.
