We establish sharp long time asymptotic behaviour for a family of entropies to defective Fokker–Planck equations and show that, much like defective finite dimensional ODEs, their decay rate is an exponential multiplied by a polynomial in time. The no... Read More about On the rates of decay to equilibrium in degenerate and defective Fokker–Planck equations.
