四维和五维非线性薛定谔方程亚临界基态的稳定性

On the stability of ground states in 4D and 5D nonlinear Schrodinger equation including subcritical cases

E. Kirr, O. Mizrak

摘要:

考虑了四维和五维空间中一类具有吸引势的非线性薛定谔方程。的非线性是本地的,但相当普遍的第一次包括亚临界和超临界(在L2)的非线性。我们证明了由空间上的周期解(束缚态)形成的中心流形对所有具有小初值的解都是吸引子。的证明取决于分散的估计,我们获得的不定常,哈密顿,线性化动力学围绕一个参数家庭的束缚态,“阴影”的非线性演化系统。我们采用的方法是对更高维度的扩展,因此不同的线性色散行为,以及我们以前的结果[10,11,7]的粗糙非线性。

英文摘要:

We consider a class of nonlinear Schrodinger equation in four and five space dimensions with an attractive potential. The nonlinearity is local but rather general encompassing for the first time both subcritical and supercritical (in L2) nonlinearities. We show that the center manifold formed by localized in space periodic in time solutions (bound states) is an attractor for all solutions with a small initial data. The proof hinges on dispersive estimates that we obtain for the time dependent, Hamiltonian, linearized dynamics around a one parameter family of bound states that "shadows" the nonlinear evolution of the system. The methods we employ are an extension to higher dimensions, hence different linear dispersive behavior, and to rougher nonlinearities of our previous results [10, 11, 7].
