Abstract : The research is concerned with the theory of infinite dimensional systems and their qualitative properties: controllability, observability, stabilizability and other related notions. Such properties may be unstable under approximation, in which case there may exist a property-gap. Considerable use is made of functional analysis, especially spectral theory in deriving several criteria for checking these system properties. As an illustration of the general theory linear systems with hereditary dependence (the most general type known to be useful) are considered. Several new results on controllability and stabilizability are presented. (Author)
