Roman O. Popovych, Nataliya M. Ivanova, Homayoon Eshraghi

摘要:

我们对形式为$iψ_t+ψ_{xx}+|ψ|^γψ+V(t,x)ψ=0$的非线性薛定谔方程进行了完全群分类,其中$V$是依赖于$t$的任意复值势,$x,$ $γ$是实非零常数.我们构造所有可能的不等价的潜力,这些方程具有非平凡的李对称性,使用代数和兼容性相结合的方法。所提出的方法可以应用于解决组分类问题的一些重要类别的微分方程出现在数学物理。

英文摘要:

We perform the complete group classification in the class of nonlinear Schrödinger equations of the form $iψ_t+ψ_{xx}+|ψ|^γψ+V(t,x)ψ=0$ where $V$ is an arbitrary complex-valued potential depending on $t$ and $x,$ $γ$ is a real non-zero constant. We construct all the possible inequivalent potentials for which these equations have non-trivial Lie symmetries using a combination of algebraic and compatibility methods. The proposed approach can be applied to solving group classification problems for a number of important classes of differential equations arising in mathematical physics.
