WebThe Boltzmann equation was given by Ludwig Boltzmann in 1872. In modern literature, the term Boltzmann equation is often in use in a more general sense, referring to any kinetic equation that shows the change of a macroscopic quantity in a thermodynamic system. These quantities can be energy, charge or particle number.
WebBoltzmann Equation. Since the Boltzmann equation is quadratic it involves only binary collision therefore an important step is to prove that other events can be excluded and this is a direct consequence of the following theorem (cf.
