Relativistic transformation of phase-space distributions [PDF]

Annales Geophysicae, 2011
We investigate the transformation of the distribution function in the relativistic case, a problem of interest in plasma when particles with high (relativistic) velocities come into play as for instance in radiation belt physics, in the electron ...
