摘要:
我们考虑了一维网格中具有立方聚焦或反聚焦非线性的离散非线性薛定谔方程。我们证明了离散Sobolev范数增长的多项式界,该界与网格步长无关。此界基于更高修改能量的构造。
英文摘要:
We consider the discrete nonlinear Schr{ö}dinger equations on a one dimensional lattice of mesh h, with a cubic focusing or defocusing nonlinearity. We prove a polynomial bound on the growth of the discrete Sobolev norms, uniformly with respect to the stepsize of the grid. This bound is based on a construction of higher modified energies.
