The Kurdyka-Łojasiewicz-Simon inequality and stabilisation in nonsmooth infinite-dimensional gradient systems

Ralph Chill, Sebastian Mildner

We state and prove a stabilisation result for solutions of abstract gradient systems associated with nonsmooth energy functions on infinite dimensional Hilbert spaces. One feature…

Weak and strong approximation of semigroups on Hilbert spaces

R. Chill, A. F. M. ter Elst

For a sequence of uniformly bounded, degenerate semigroups on a Hilbert space, we compare various types of convergences to a limit semigroup. Among others, we show that convergence…

Operators $L^{1} (R_{+}) \to X$ and the norm continuity problem for semigroups

R. Chill, Yu. Tomilov

We present a new method for constructing $C_{0}$ -semigroups for which properties of the resolvent of the generator and continuity properties of the semigroup in the operator-norm top…
