On the spectral problem and fractional diffusion limit for Fokker-Planck with(-out) drift and for a general heavy tail equilibrium

Dahmane Dechicha

This paper is devoted to the study of a kinetic Fokker-Planck equation with general heavy-tailed equilibrium without an explicit formula, such as $C_{\hat{I}}^2⟨v{⟩}^{-{\hat{I}}^2}$, in…
