DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PHSeminar/1/
 ">Port-Hamiltonian systems: algebraic\, geometric and operator theoretic r
 epresentations</a>\nby Volker Mehrmann (TU Berlin) as part of Port-Hamilto
 nian Seminar (pH Seminar)\n\n\nAbstract\nDifferent representations of diss
 ipative Hamiltonian and port-Hamiltonian differential-algebraic equations 
 (DAE) systems are presented and compared. Using global geometric and algeb
 raic points of view\, translations between the different representations a
 re presented. The results also apply in the Hilbert space setting of linea
 r operator equations. Characterizations are also derived when a general DA
 E system can be transformed into one of these structured representations. 
 Approaches for computing the structural information and the described tran
 sformations are derived that can be directly implemented as numerical meth
 ods. The results are demonstrated with a large number of examples.\n\nJoin
 t work partly with Arjan van der Schaft and partly with Hans Zwart\n
