WebDec 20, 2024 · The Boltzmann/Planck definition is that W is the number of states accessible to the system at its energy E (also called the surface entropy). The Gibbs/Hertz definition is that W is the number of states of the system up to the energy E (also called the volume entropy). WebThe Fokker-Planck (FP) equation approach is used for simplifying the collision integrals in the rhs of Boltzmann equation.
