Exact Lattice Boltzmann Equation

Physical Review Letters, 2013
The lattice Boltzmann equation is derived from the Bhatnagar-Gross-Krook kinetic equation using the Euler-Maclaurin integration formula. Unlike previous attempts to connect the lattice Boltzmann method with the kinetic theory, the result is free of any relaxation-type approximation.

Quasiparticle Boltzmann equation in semiconductors

Physical Review B, 1994
The quasiparticle approximation and corrections beyond it are derived from expansion in the spirit of the virial corrections. This way, the Boltzmann equation for electrons in semiconductors is recovered from the nonequilibrium Green's functions without unjustified neglect of the former theory.

THE BOLTZMANN EQUATION IS A RENORMALIZATION GROUP EQUATION

International Journal of Modern Physics B, 2000
It is known that renormalization group (RG) approaches to partial differential equations give reduced equations, e.g., amplitude equations, as renormalization group equations. Therefore, equations governing slow or global behaviors ought to be derived RG-theoretically.
