在这篇文章中,我们考虑动力学导数非线性薛定谔方程(KDNLS),它是作为考虑波调制和离子之间的共振相互作用的等离子体传播模型而产生的。与标准的导数NLS方程相比,KDNLS方程不守恒质量和能量。尽管如此,KDNLS的耗散结构使我们能够在能量空间中显示一个先验界和其解的L2范数的下界,正如我们在本说明中看到的。结合局部适定性结果,我们计划在即将发表的论文中展示,这些界限将在能量空间中给出小初始数据的全局存在性结果。
In this note, we consider the kinetic derivative nonlinear Schrödinger equation (KDNLS), which arises as a model of propagation of a plasma taking the effect of the resonant interaction between the wave modulation and the ions into account. In contrast to the standard derivative NLS equation, KDNLS does not conserve the mass and the energy. Nevertheless, the dissipative structure of KDNLS enables us to show an a priori bound in the energy space and a lower bound of theL2norm for its solution, as we see in this note. Combined with the local wellposedness result, which we plan to show in a forthcoming paper, these bounds will give a global existence result in the energy space for small initial data.
