Some comments on observability and related topics
Robert Rosén · International Journal of Systems Science · 1973
Some of the problems involved in finding a set of state variables for a dynamical system are formulated. Particular attention is given to the definition of topologies in which these presumptive state variables become jointly continuous, or in which a particular system dynamics is continuous. These ideas are illustrated in a number of particular examples with a bearing also on recursive function theory and on pattern recognition.
