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…

Numerical Range and Quadratic Numerical Range for Damped Systems

Birgit Jacob, Christiane Tretter, Carsten Trunk +1

We prove new enclosures for the spectrum of non-selfadjoint operator matrices associated with second order linear differential equations $\ddot{z}(t) + D \dot{z} (t) + A_0 z(t) = 0…
