本文研究了二阶导数非线性Schr dinger方程的Cauchy问题[公式见正文]我们假设初始值在加权Sobolev空间H3,1(R)中是小的,则我们证明了Cauchy问题(R)存在整体时间上的小解.我们研究了解的大时间行为,并构造了大时间值的修正渐近性。
In this paper, we study the Cauchy problem for the quadratic derivative nonlinear Schrödinger equation [Formula: see text] We suppose that the initial data are small in the weighted Sobolev space H3,1( R ) then we prove that there exist global in time small solutions to the Cauchy problem (∗) . We study the large time behavior of solutions and construct the modified asymptotics for large time values.
