Analytic constraints and readability for analytic input-output operators

摘要

For input-output (i-o) operators, an equivalence is shown between readability by state-space systems and the existence of analytic constraints on higher-order deriva-tives of i-o signals. This provides a precise characterization of realizability, extend-ing to the general analytic case the previous work that dealt with the equivalence between algebraic realizability and algebraic i-o equations.
