我们构造了空间维N geq 7$中能量临界聚焦非线性薛定谔方程的纯双泡。构造的解决方案是全球性的(至少)一个时间方向和方法的叠加两个定态都集中在原点,其长度尺度的比率收敛到0 $。其中一个泡沫的发展规模为1美元,而另一个泡沫的长度规模则以1美元的速度收敛到0美元。|不|^{-frac{2}{N-6}}$。两个气泡的相位形成直角。
We construct pure two-bubbles for the energy-critical focusing nonlinear Schr"odinger equation in space dimension $N geq 7$. The constructed solution is global in (at least) one time direction and approaches a superposition of two stationary states both centered at the origin, with the ratio of their length scales converging to $0$. One of the bubbles develops at scale $1$, whereas the length scale of the other converges to $0$ at rate $|t|^{-frac{2}{N-6}}$. The phases of the two bubbles form the right angle.
