We first recall the definition of an implicit system (sometimes also called ”generalized state-space system”) and its most important properties. We then define the notion of inverse system, proving existence and uniqueness from an external point of view. Next we show how the theory of implicit systems yields inverse systems and some of their properties in an easy way. For instance we examine the conditions under which the inverse system is minimal, and show also that a state-space system is right or left invertible if some blocks are missing in its Kronecker form.
