Some Liouville theorems for stationary Navier-Stokes equations in Lebesgue and Morrey spaces

Abstract Uniqueness of Leray solutions of the 3D Navier-Stokes equations is a challenging open problem. In this article we will study this problem for the 3D stationary Navier-Stokes equations in the whole space R 3 . Under some additional hypotheses, stated in terms of Lebesgue and Morrey spaces, we will show that the trivial solution U → = 0 is the unique solution. This type of results are known as Liouville theorems.
