Frank Merle, Pierre Raphaël, Jeremie Szeftel

AI总结:

针对质量超临界且能量次临界范围的非线性Schrödinger方程,本文证明了径向对称初始数据下爆破速度的普适上界,并证明该上界精确且在塌缩环爆破解族上达到。

摘要:

我们考虑非线性Schrödinger方程$i\partial_tu+Δu+u|u|^{p-1}=0$,维度$N\geq 2$,处于质量超临界且能量次临界范围$1+\frac 4N<p<\min\{\frac{N+2}{N-2},5\}$。对于具有径向对称性的初始数据$u_0\in H^1$,我们证明了爆破速度的普适上界。我们随后证明该上界是精确的,并在Gavish, Fibich和Wang首次形式预测的塌缩环爆破解族上达到。

英文摘要:

We consider the nonlinear Schrödinger equation $i\partial_tu+Δu+u|u|^{p-1}=0$ in dimension $N\geq 2$ and in the mass super critical and energy subcritical range $1+\frac 4N<p<\min\{\frac{N+2}{N-2},5\}.$ For initial data $u_0\in H^1$ with radial symmetry, we prove a universal upper bound on the blow up speed. We then prove that this bound is sharp and attained on a family of collapsing ring blow up solutions first formally predicted by Gavish, Fibich and Wang.
