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…

Observability and null-controllability for parabolic equations in $L_{p}$ -spaces

Clemens Bombach, Dennis Gallaun, Christian Seifert +1

We study (approximate) null-controllability of parabolic equations in $L_{p} (R^{d})$ and provide explicit bounds on the control cost. In particular we consider systems of the…

Sufficient criteria and sharp geometric conditions for observability in Banach spaces

Dennis Gallaun, Christian Seifert, Martin Tautenhahn

Let $X, Y$ be Banach spaces, $(S_{t})_{t \geq 0}$ a $C_{0}$ -semigroup on $X$ , $- A$ the corresponding infinitesimal generator on $X$ , $C$ a bounded linear operator from $X$ to $Y$ , and $…
