Analytic constraints and realizability for analytic input-output operators
Mathematics Department, Florida Atlantic University Baca Raton, FL 33431
For input-output (i-o) operators, an equivalence is shown between realizability by state-space systems and the existence of analytic constrainsts on higher-order derivatives of i-o signals. This provides a precise characterization of realizability, extending to the general analytic case the previous work that dealt with the equivalence between algebraic realizability and algebraic i-o equations.
