Enhanced dissipation for the Kolmogorov flow via the hypocoercivity method Dedicated to Professor Jean-Yves Chemin on the Occasion of His 60th Birthday

In this paper, we solve Beck and Wayne's conjecture on the optimal enhanced dissipation rate for the 2-D linearized Navier-Stokes equations around the bar state called the Kolmogorov flow by developing the hypocoercivity method introduced by Villani(2009).
