In this thesis we study the eigenvalues of linear matrix pencils and their behavior under perturbations of the pencil coefficients. In particular we address (i)

This thesis considers the linear-quadratic optimal control problem for differential-algebraic systems. In this first part, a complete theoretical analysis of th

Differential-algebraic equations are the most natural way to mathematically model many complex systems in science and engineering. Once the model is derived, it
