Abstract

We consider differential operators A that can be represented by means of a so-called closure relation in terms of a simpler operator \( A_{ {\text {ext} } } \) defined on a larger space. We analyse how the spectral properties of \( A \) and \( A_{ {\text {ext} } } \) are related and give sufficient conditions for exponential stability of the semigroup generated by \( A \) in terms of the semigroup generated by \( A_{ {\text {ext} } } \). As applications we study the long-term behaviour of a coupled wave–heat system on an interval, parabolic equations on bounded domains that are coupled by matrix-valued potentials, and of linear infinite-dimensional port-Hamiltonian systems with dissipation on an interval.
