Abstract: | We show that continuous dependence on initial data of solutions to the Euler equations of incompressible hydrodynamics is optimal. More precisely, we prove that the data-to-solution map is not uniformly continuous in Sobolev H s (Ω) topology for any ${s \in \mathbb{R}}We show that continuous dependence on initial data of solutions to the Euler equations of incompressible hydrodynamics is
