Description

Different variational approaches for the problem of collisional transport in a magnetically confined magnetoplasma are discussed, and approximate methods of solution are pointed out. In particular, an approach analogous to the well known Rayleigh-Ritz method is proposed, yielding an energy-convergent approximate solution for the relevant drift Fokker-Planck equation. Selected applications to the investigation of magnetoplasmas of arbitrary of collisionality are briefly discussed. (Author)
