The projection operator in a Hilbert space and its directional derivative. Consequences for the theory of projected dynamical systems

In the first part of this paper we present a representation theorem for the directional derivative of the metric projection operator in an arbitrary Hilbert space. As a consequence of the representation theorem, we present in the second part the development of the theory of projected dynamical syste...
