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). | 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 theory takes account of all particle motion associated with toroidal geometry; specifically, ''∇ B'' and curvature drifts, trapped and passing particles (banana orbits). | |||
The theory is valid for all collisionality regimes, and includes effects due to resistivity and viscosity. An important prediction of the theory is the [[Bootstrap current|bootstrap current]]. | |||
