In order to become worldly things, that is, deeds and facts and events and patterns of

Stability and stabilization of linear port-Hamiltonian systems on infinite-dimensional spaces
are investigated. This class is general enough to include models of beams and waves as …

Hyperbolic partial differential equations on a one-dimensional spatial domain are studied.
This class of systems includes models of beams and waves as well as the transport equation …

From the very start of the science of mechanics strings and beams played a crucial role in
the research, starting from the consideration of eg the dynamics of a mass attached to a …

We study hyperbolic systems of one-dimensional partial differential equations under
general, possibly non-local boundary conditions. A large class of evolution equations, either …

We prove well-posedness for very general linear wave-and diffusion equations on compact
or non-compact metric graphs allowing various different conditions in the vertices. More …

Boundary feedback stabilization of linear infinite dimensional port-Hamiltonian systems on
an interval is considered. Generation and stability results already known for linear feedback …

Given an energy-dissipating port-Hamiltonian system, we characterise the exponential
decay of the energy via the model ingredients under mild conditions on the Hamiltonian …

Using the semigroup approach to abstract boundary control problems we characterize the
space of all exactly reachable states. Moreover, we study the situation when the controls of …

We study port-Hamiltonian systems on a family of intervals and characterize all boundary
conditions leading to m-accretive realizations of the port-Hamiltonian operator and thus to …
