Discretization of inherent ODEs and the geometric integration of DAEs with symmetries
Peter Kunkel, Volker Mehrmann
Discretization methods for differential-algebraic equations (DAEs) are considered that are based on the integration of an associated inherent ordinary differential equation (ODE).…

Local and global canonical forms for differential-algebraic equations with symmetries
Peter Kunkel, Volker Mehrmann
Linear time-varying differential-algebraic equations with symmetries are studied. The structures that we address are self-adjoint and skew-adjoint systems. Local and global canonic…
