带位势的(1+1)维三次薛定谔方程的Lie对称性

Lie Symmetries of (1+1)-Dimensional Cubic Schrödinger Equation with Potential

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

摘要:

我们在形式为$iψ_t+ψ_{xx}+ψ^2ψ^*+V(t,x)ψ=0$的三次薛定谔方程类中进行完全群分类,其中$V$是依赖于$t$和$x$的任意复值势。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,同时使用代数和兼容性的方法。我们的分类基本上修正了关于这个问题的早期著作。

英文摘要:

We perform the complete group classification in the class of cubic Schrödinger equations of the form $iψ_t+ψ_{xx}+ψ^2ψ^*+V(t,x)ψ=0$ where $V$ is an arbitrary complex-valued potential depending on $t$ and $x$. We construct all possible inequivalent potentials for which these equations have non-trivial Lie symmetries using algebraic and compatibility methods simultaneously. Our classification essentially amends earlier works on the subject.
