摘要:

研究了具有临界长程非线性项的非齐次非线性薛定谔方程的终态问题。给定一个规定的渐近轮廓,它有一个对数相位校正相比,自由的发展,我们构造了一个唯一的整体解决方案,收敛到该轮廓。作为结果,修正的波算子的存在性局部小散射数据。我们还研究了径向对称下临界平方反比势的情形。特别地,我们构造了三维空间中具有临界平方反比势的长程非线性薛定谔方程在径向对称下的修正波算子.

英文摘要:

We consider the final state problem for the inhomogeneous nonlinear Schrödinger equation with a critical long-range nonlinearity. Given a prescribed asymptotic profile, which has a logarithmic phase correction compared with the free evolution, we construct a unique global solution which converges to the profile. As a consequence, the existence of modified wave operators for localized small scattering data is obtained. We also study the same problem for the case with the critical inverse-square potential under the radial symmetry. In particular, we construct the modified wave operators for the long-range nonlinear Schrödinger equation with the critical inverse-square potential in three space dimensions, under the radial symmetry.
