On the ill-posedness of the Prandtl equation

Above all, the local in time well-posedness of the Prandtl equation for smooth (say Sobolev) initial data has been so far an open problem.. Interestingly, for a smooth initial

Infinite Prandtl number limit of Rayleigh-Benard convection

In order to derive the effective dynamics for the Boussinesq system at large Prandtl number, we recognize that the large Prandtl number problem is really a problem involving two

THE RATE OF CONVERGENCE FOR THE RENEWAL THEOREM IN R d.

In this section, we use this construction (that also works for strongly irreducible and proximal subgroups rather than Zariski-dense ones) to prove a technical result that will allow
