Abstract:

In this paper we address the Cauchy problem for the incompressible Euler equations in the periodic setting. Based on estimates developed in Buckmaster-De Lellis-Isett-Székelyhidi, we prove that the set of H\"older $1\slash 5-\eps$ wild initial data is dense in $L^2$, where we call an initial datum wild if it admits infinitely many admissible H\"older $1\slash 5-\eps$ weak solutions. We also introduce a new set of stationary flows which we use as a perturbation profile instead of Beltrami flows to recover arbitrary Reynolds stresses.
