Abstract

In this thesis, continuous time, autonomous, observable dynamical systems are studied. The main problem considered is whether sampling at discrete times preserves observability. The discrete observability problem is shown to be equivalent to the general theory of linear interpolation. The mathematical theory used in this paper is Polya's property W which is used to produce several new results. In addition, the problem of discrete sampling is also interpreted as an n-point boundary value problem and as a problem of independence in the dual space.
