A note on the Lumer--Phillips theorem for bi-continuous semigroups
Karsten Kruse, Christian Seifert
Given a Banach space and an additional coarser Hausdorff locally convex topology on we characterise the generators of -bi-continuous semigroups in the spirit of the…

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…

Final State Observability in Banach spaces with applications to Subordination and Semigroups induced by L{é}vy processes
Dennis Gallaun, Jan Meichsner, Christian Seifert
This paper generalizes the abstract method of proving an observability estimate by combining an uncertainty principle and a dissipation estimate. In these estimates we allow for a…
