In this paper we study the time-dependent discrete nonlinear Schrödinger equation with complex, not necessarily bounded, potential and sufficiently general nonlinearity on a multi dimensional lattice. Under natural assumptions we prove the global well-posedness in weighted spaces. In the dissipative case we obtain a result on the existence of global compact attractor in such spaces.

具有复势的离散非线性薛定谔方程的初值问题
在本文中,我们研究了多维晶格上具有复杂的、不一定有界的、潜在的和足够一般的非线性的时间相关离散非线性薛定谔方程。在自然假设下,我们证明了加权的全局适定性空格。在耗散的情况下,我们得到了在这样的空间中存在全局紧致吸引子的结果。
