P. Degond et M. Lemou, DISPERSION-RELATIONS FOR THE LINEARIZED FOKKER-PLANCK EQUATION, Archive for Rational Mechanics and Analysis, 138(2), 1997, pp. 137-167
We analyze the spectral properties and dispersion relations for the li
nearized Fokker-Planck operator in the case of hard potentials, as in
ELLIS & PINSKY's work [7] on the Boltzmann equation. Results similar t
o those in [7] are obtained for the Fokker-Planck operator although th
e presence of a diffusion operator instead of a multiplication operato
r introduces many additional technical difficulties.
