Perturbations of periodic Sturm--Liouville operators

Jussi Behrndt, Philipp Schmitz, Gerald Teschl +1

We study perturbations of the self-adjoint periodic Sturm--Liouville operator \[ A_0 = \frac{1}{r_0}\left(-\frac{\mathrm d}{\mathrm dx} p_0 \frac{\mathrm d}{\mathrm dx} + q_0\right…

Spectral bounds for singular indefinite Sturm-Liouville operators with $L^{1}$ --potentials

Jussi Behrndt, Philipp Schmitz, Carsten Trunk

The spectrum of the singular indefinite Sturm-Liouville operator $A = sgn (\cdot) (- \frac{d ^{2}}{d x ^{2}} + q)$ with a real potential $q \in L^{1} (R)$ covers the…
