Stabilization by Noise of Navier–Stokes Equations

Abstract

The stochastic stabilization of Navier–Stokes equations is an alternative approach to stabilization techniques described in Chap. 3, which have two important advantages: the simplicity of the stabilizable feedback law and its robustness to (deterministic and stochastic) perturbations. A long time ago, it was observed that the noise might stabilize the finite and infinite-dimensional dynamical systems and several empirical observations in fluid dynamics suggested that noise might have a dissipation effect comparable with increasing the viscosity of fluid. This is exactly what will be rigorously proven here by designing stabilizing noise feedback controller with internal or boundary support.
