Robustness of flat bands on the perturbed Kagome and the perturbed Super-Kagome lattice
Joachim Kerner, Matthias Täufer, Jens Wintermayr
We study spectral properties of perturbed discrete Laplacians on two-dimensional Archimedean tilings. The perturbation manifests itself in the introduction of non-trivial edge weig…
A refinement of Baillon's theorem on maximal regularity
Birgit Jacob, Felix Schwenninger, Jens Wintermayr
By Baillon's result, it is known that maximal regularity with respect to the space of continuous functions is rare; it implies that either the involved semigroup generator is a bou…
Perturbations of Positive Semigroups on AM-Spaces
A. Bátkai, B. Jacob, J. Voigt +1
We consider positive perturbations of positive semigroups on AM-spaces and prove a result which is the dual counterpart of a famous perturbation result of Desch in AL-spaces. As an…
Desch-Schappacher Perturbation of One-Parameter Semigroups on Locally Convex Spaces
Birgit Jacob, Sven-Ake Wegner, Jens Wintermayr
We prove a Desch-Schappacher type perturbation theorem for strongly continuous and locally equicontinuous one-parameter semigroups which are defined on a sequentially complete loca…
