Enhanced dissipation via the Malliavin calculus

Year: 2025

Type: article

Abstract: In this work we investigate the phenomenon of enhanced dissipation using techniques from the Malliavin Calculus. In particular, we construct a concise, elementary argument, that allows us to recover the well-known enhanced dissipation timescale for shear flows, first obtained in [2], as well as the precise hypoelliptic regularisation in Fourier space.
