Description

The book deals with the random perturbation of PDEs which lack well-posedness, mainly because of their non-uniqueness, in some cases because of blow-up.

The aim is to show that noise may restore uniqueness or prevent blow-up.

This is not a general or easy-to-apply rule, and the theory presented in the book is in fact a series of examples with a few unifying ideas.

The role of additive and bilinear multiplicative noise is described and a variety of examples are included, from abstract parabolic evolution equations with non-Lipschitz nonlinearities to particular fluid dynamic models, like the dyadic model, linear transport equations and motion of point vortices.
