Rezumat: The previous discussions have prepared the solution of the neoclassical drift-kinetic equation in various regimes. It remained to pay more attention to the collision operators and go further to viscosity and its relation with the fluxes. It has been formulated a request to stop for a while on the variation of the parameters in the magnetic surface, a purely neoclassical problem, which however is essential to understand spontaneous spin-up and the equilibrium flows. Then some of the previous subjects will be repeated in this fourth meeting: diamagnetic flow, Pfirsch Schluter flow, geometric inertial factor, spontaneous spin-up, magnetic pumping. We will focus on the Stringer solution of the drift-kinetic equation for the perturbation to the equilibrium function, which reflects the neoclassical poloidal variation. We will also mention other approaches (Stacey, Shaing, Helander).
