“…We refer to Section III for the precise assumptions on P 1 , G 0 , W B,1 W B,0 , W C,1 W C,0 and H. This class of systems describes a special class of port-Hamiltonian systems, which however is rich enough to cover in particular the wave equation, the transport equation and the Timoshenko beam equation, and also coupled beam and wave equations. For more information on this class of port-Hamiltonian systems we refer to the first paper on this topic, [15], the monograph [11] and the survey [12].…”
