On the perturbed periodic Schrödinger operators with separate resonant embedded eigenvalues

Kang Lyu, Chuanfu Yang

In this paper, we consider Schrödinger operators on $L^2(0,\infty )$ given by \begin{align} Hu=(H_0+V)u=-u^{\prime\prime}+V_0u+Vu,\nonumber \end{align} where $V_0$ is real, $1$-peri…
