本文研究了离散非线性随机薛定谔方程[式:见正文]在[式:见正文]上的解,其中0 <ε,δ ε 1,Δ为离散Laplacian,V为随机势.我们将随机势V固定在一个好的集合中。然后,我们用小振幅作为参数构造了非线性随机薛定谔方程的拟周期解。
In this paper, we study the discrete nonlinear random Schrödinger equation [Formula: see text] on [Formula: see text], where 0 < ɛ, δ ≪ 1, Δ is the discrete Laplacian, and V is the random potential. We fix the random potential V in a good set. Then, we use small amplitudes as parameters to construct quasiperiodic solutions of the nonlinear random Schrödinger equation.
