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…
Crouzeix's Conjecture and related problems
Kelly Bickel, Pamela Gorkin, Anne Greenbaum +3
In this paper, we establish several results related to Crouzeix's conjecture. We show that the conjecture holds for contractions with eigenvalues that are sufficiently well-separat…
Remarks on input-to-state stability of collocated systems with saturated feedback
Birgit Jacob, Felix L. Schwenninger, Lukas A. Vorberg
We investigate input-to-state stability (ISS) of infinite-dimensional collocated control systems subject to saturated feedback. Here, the unsaturated closed loop is dissipative and…
