Details
Since the famous work of V. Scheffer about 20 years ago,
it has been known that the Cauchy problem for the incompressible Euler
equations has non-unique weak solutions. Recently, De Lellis and
Szekelyhidi demonstrated that this phenomenon can be viewed as an
instance of the so-called h-principle, thereby providing a shorter and
more general proof of the non-uniqueness. In this talk I will briefly
review their method and then present some subsequent results, including
global existence and non-uniqueness for 3D Euler, the approximation of
measure-valued solutions by weak ones, and non-uniqueness for shear
flow initial data.
