This book studies observation and control operators for linear systems where the free evolution of the state can be described by an operator semigroup on aHilbert space. The emphasis is on well-posedness, observability and controllability properties. The abstract results are supported by a large number of examples coming mostly from partial differential equations. These examples are worked out in detail. This book is meant to be an elementary introduction in this theory. The first meaning of ‘elementary'' is that the text is aimed to be accessible to any reader familiar with linear algebra, calculus, the basics of Hilbert spaces and differential equations. We introduce everything needed on operator semigroups and most of the background used is summarized in the Appendices, often with proofs. The second meaning of ‘elementary'' is that we only cover results for which we can provide complete proofs. Book is to large extentself-contained Attempts to unify two approaches traditionally different, one using essentially abstract functional analysis and the other based on techniques coming from partial differential equations Main exact observability resultsare obtained by combining functional analysis with various methods such as multipliers, Ingham-Beurling-type inequalities and Carleman estimates INDICE: Preface.- 1.
