Alternative Proof of the Gearhart-Prüss Theorem

摘要

In this paper, we provide an alternative proof of the Gearhart-Prüss theorem for \(C_0\) C 0 -semigroups on Hilbert spaces. The approach relies on a characterization of the uniform exponential stability via an estimate of a tempered distribution defined in terms of the resolvent.
