Spectral approximation of generalized Schrödinger operators via approximation of subwords

Fabian Gabel, Dennis Gallaun, Julian Großmann +2

We demonstrate criteria, purely based on finite subwords of the potential, to guarantee spectral inclusion as well as Hausdorff approximation of pseudospectra or even spectra of ge…

The Stokes operator in two-dimensional bounded Lipschitz domains

Fabian Gabel, Patrick Tolksdorf

We consider the Stokes resolvent problem in a two-dimensional bounded Lipschitz domain subject to homogeneous Dirichlet boundary conditions. We prove -resolvent e…

Observability for Non-autonomous Systems

Clemens Bombach, Fabian Gabel, Christian Seifert +1

We study non-autonomous observation systems \begin{align*} \dot{x}(t) = A(t) x(t),\quad y(t) = C(t) x(t),\quad x(0) = x_0\in X, \end{align*} where is a strongly measurable…
