我们考虑$\mathbb R$上的拟线性薛定谔方程,当解为零时,色散效应退化。我们首先证明了充分光滑,空间局部化,退化的初始数据的局部适定性。作为一个推论,在聚焦的情况下,我们得到了一个短时间的稳定性结果的能量最小化紧凑呼吸。
We consider a quasilinear Schrodinger equation on $\mathbb R$ for which the dispersive effects degenerate when the solution vanishes. We first prove local well-posedness for sufficiently smooth, spatially localized, degenerate initial data. As a corollary in the focusing case we obtain a short time stability result for the energy-minimizing compact breather.
