# Who was the first to prove the Boltzman H-theorem for the Landau kinetic equation?

Who has proved Boltzmann's H-theorem (which tells that entropy of a closed system grows as the system approaches thermal equilibrium) for the kinetic equation with Landau collisions operator? One proof is provided by F. Hinton in 1st volume of "Basic plasma physics" (edited by Sudan and Galeev) but I wonder if Hinton was the first.

UPDATE: I asked same question on https://www.researchgate.net/post/Who_was_first_to_prove_the_Boltzman_H-theorem_for_the_Landau_kinetic_equation and was answered that a derivation was provided by N.Bogolubov but I don't believe in that.

• Out of curiosity, why don't you believe the claim that said derivation existed? – HDE 226868 Jan 15 '16 at 0:22
