Nonuniqueness of the $2$ D Euler Evolutions with $L^{1} \cap L^{p}$ Vorticity

Thomas Y. Hou, Xiang Qin, Peicong Song +1

For each prescribed $1 < p < \infty$ , we construct a compactly supported initial vorticity in $L^{1} (R^{2}) \cap L^{p} (R^{2})$ that admits two distinct evolutions under the un…

A Sharp Uniqueness-Nonuniqueness Dichotomy for Neutral Vortex Arrays in $2$ D Euler Equations

Thomas Y. Hou, Xiang Qin, Peicong Song +1

We establish a sharp uniqueness--nonuniqueness criterion for the two-dimensional incompressible Euler equations within a class of stationary arrays of disjoint neutral vortices. Le…
