Questions concerning differential-algebraic operators: Toward a reliable direct numerical treatment of differential-algebraic equations
Michael Hanke, Roswitha März
The nature of so-called differential-algebraic operators and their approximations is constitutive for the direct treatment of higher-index differential-algebraic equations. We trea…

A least-squares collocation method for nonlinear higher-index differential-algebraic equations
Michael Hanke, Roswitha März
We introduce a direct numerical treatment of nonlinear higher-index differential-algebraic equations by means of overdetermined polynomial least-squares collocation. The procedure…
