Nonlocal Lagrange formalism in the thermodynamics of irreversible processes: variational procedures for kinetic equations

Sievers, B.; Anthony, K.-H. - In: Physica A: Statistical Mechanics and its Applications 225 (1996) 1, pp. 89-128

This paper is concerned with generalizations of the known local Lagrange formalism of first order. It will be applied to kinetic equations like the Fokker-Planck equation and the Boltzmann equation. In the latter case nonlocal methods are necessary from the very beginning. Nevertheless, in the...
