External Properness

Moisés Bonilla, Michel Malabre and Jaime Pacheco

Abstract:

In this paper, we revisit the structural concept of properness. We distinguish between the properness of the whole system, here called internal properness, and the properness of the ``observable part" of the system. We give geometric characterizations for this last properness concept, namely external properness.

Keywords: properness; linear systems; implicit systems;
