Abstract

In this paper we consider the incompressible Euler equation on the Sobolev space $H^s (\mathbb{R}^n), s \gt n/2 + 1$, and show that for any $T \gt 0$ its solution map $u_0 \mapsto u(T )$, mapping the initial value to the value at time $T$, is nowhere locally uniformly continuous and nowhere differentiable.
