Abstract

We prove local blow-up criterion for smooth axisymmetric solutions to the 3D incompressible Euler equation. If the vorticity satisfies \intl0t(tt)ω(t)L(B(x,R0))dt<+ \intl_{0}^{t_*} (t_*-t) \| \omega (t)\|_{ L^\infty(B(x_{ \ast}, R_0))} dt <+\infty for a ball B(x,R0)B(x_{ \ast}, R_0) away from the axis of symmetry, then there exists no singularity at t=tt=t_* in the torus T(x,R)T(x_*, R) generated by rotation of the ball B(x,R0)B(x_{ \ast}, R_0) around the axis. This implies that possible singularity at t=tt=t_* in the torus T(x,R)T(x_*, R) is excluded if the vorticity satisfies the blow-up rate \o(t)L(T(x,R))=O(1(tt)γ) \|\o (t)\|_{L^\infty (T(x_*, R))}= O\left(\frac{1}{(t_*-t)^\gamma}\right) as ttt\to t_*, where γ<2\gamma <2 and the torus T(x,R)T(x_*, R) does not touch the axis.
