The main goal of Neoclassical transport theory is to provide a closed set of equations for the time evolution of these moments, for each particle species. | The main goal of Neoclassical transport theory is to provide a closed set of equations for the time evolution of these moments, for each particle species. Since the determination of any moment requieres knowledge of the next order moment, this requires truncating the set of moments (''closure'' of the set of equations). | ||
