We prove the completeness of the system of eigenfunctions of the complex Schrodinger operator $L=-d^2/dx^2+cx^{2/3}$ on the semiaxis in $L_2(0,+\infty)$ with Dirichlet boundary conditions for all $c$: $|\arg c|<\pi/2+\theta_0$, where $\theta_0\in(\pi/10,\pi/9)$ is defined as the only solution of a certain transcendental equation.

复杂薛定谔算子的本征函数系统的完备性定理 Lc=−d2/dx2+cx2/3

我们用狄利克雷证明了半轴上复杂薛定谔算子$L=-d^2/dx^2+cx^{2/3}$的本征函数系统的完备性所有 $c$ 的边界条件:$|\arg c|<\pi/2+\theta_0$,其中 $\theta_0\in(\pi/10,\pi/9)$ 定义为 a 的唯一解一定的超越方程。
