ISS and integral ISS coincide for linear systems with bounded inputs
Sahiba Arora, Philip Preußler, Felix Schwenninger
We show that input-to-state stability (ISS) and integral input-to-state stability (integral ISS) with respect to the space of essentially bounded functions are equivalent propertie…

Implications of structured continuous maximal regularity
Philip Preußler, Felix L. Schwenninger
We study how maximal regularity estimates with respect to the continuous functions improve automatically in cases where the spatial norm is fundamentally different from the supremu…

On checking -admissibility for parabolic control systems
Philip Preußler, Felix L. Schwenninger
In this note we discuss the difficulty of verifying -admissibility for -- that even manifests in the presence of a self-adjoint semigroup generator on a Hil…
