Wandering solutions of Euler's D-2 equation (Q1178106)

The author proves that the flow associated with the Euler problem \[ (\partial v/\partial t)+v\nabla v=-\nabla p,\quad\text{div} v=0, \] \(\langle n,v\rangle=0\) (on \(\partial\Omega\times\mathbb{R})\), \(v(0,x)=\varphi(x)\) (in \(\Omega)\) does not have the domain restoration property in \(C^ 1\).
