Abstract

Our main goal is to study constrained systems. Applications for this class of systems can be found in physical models, such as electrical circuits. It is also possible to find constrained systems in another mathematical contexts, for example, in the study of the flows of smooth vector fields on invariant manifolds. We intend to investigate how we can describe these flows by using such systems. We also intend to study systems with singular impasse manifolds. For this, we will apply desingularization techniques and obtain a new system with regular impasse manifold which is equivalent to the first one.
