Non-uniqueness and h-Principle for Holder-Continuous Weak Solutions of the Euler Equations

In this paper we address the Cauchy problem for the incompressible Euler equations in the periodic setting. We prove that the set of Holder wild initial data is dense in , where we call an initial datum wild if it admits infinitely many admissible Holder weak solutions. We also introduce a new set of stationary flows which we use as a perturbation profile instead of Beltrami flows in order to show that a general form of the h-principle applies to Holder-continuous weak solutions of the Euler equations. Our result indicates that in a deterministic theory of three dimensional turbulence the Reynolds stress tensor can be arbitrary and need not satisfy any additional closure relation.
