具有非线性阻尼的非线性Schrodinger型方程

On nonlinear Schrodinger type equations with nonlinear damping

Paolo Antonelli, Rémi Carles, Christof Sparber

摘要:

本文研究了一类带非线性阻尼项的非线性薛定谔方程。我们表明,非线性阻尼防止有限时间爆破在几种情况下,我们描述。我们还证明了在所有空间方向上的二次约束的存在驱动我们的模型的解决方案为零的大时间。在没有外部潜在的情况下,我们证明了解决方案可能不会去零大的时间由于(非平凡)散射。

英文摘要:

We consider equations of nonlinear Schrodinger type augmented by nonlinear damping terms. We show that nonlinear damping prevents finite time blow-up in several situations, which we describe. We also prove that the presence of a quadratic confinement in all spatial directions drives the solution of our model to zero for large time. In the case without external potential we prove that the solution may not go to zero for large time due to (non-trivial) scattering.
