报告摘要:We study a sign-changing unstable free boundary problem arising from the boundary regularity of rotating vortex patches in the 2D incompressible Euler equations. By establishing a new Weiss-type monotonicity formula, we obtain a complete classification of singular points. As a consequence, we prove that for a Lipschitz rotating vortex patch, the only possible singularities on the boundary are of 90degree corner type, while the remainder of the boundary is smooth.
