English abstract:
We establish sharp long time asymptotic behaviour for a family of entropies to defective Fokker-Planck equations and show that, much like de-fective finite dimensional ODEs, their decay rate is an exponential multiplied by a polynomial in time. The novelty of our study lies in the amalgamation of spectral theory and a quantitative non-symmetric hypercontractivity result, as opposed to the usual approach of the entropy method.

Fokker-Planck equations, Spectral Theory, non-symmetric hypercon-tractivity, long time behaviour.
