Abstract:
The spectrum of the perturbed polyharmonic operator $H = (-\Delta )^l + V$ in $\textsf {L}^2(\mathbb R^d)$ with a limit-periodic potential $V$ is studied. It is shown that if $V$ is periodic in one direction in $\mathbb R^d$ and $8l > d+3$, $d \not = 1 ({mod}4)$, then the spectrum of $H$ contains a semiaxis. The proof is based on the properties of periodic operators.References
