Analysis and numerical solution of over- and underdeterminated nonlinear differential-algebraic systems

We discuss over­ and underdetermined systems of nonlinear differential­algebraic equations. Such equations arise in many applications in circuit and multibo­ dy system simulation,or in the solution of control problems. We give a general (local) existence and uniqueness theory and apply the results to nonlinear control problems. We also obtain new numerical methods and a new in­ dex reduction technique for the numerical treatment of differential­algebraic systems with extra structure.These include multibody systems and circuit simulation problems and semidiscretized Navier­Stokes equations.
