review text: The author considers a class of unbounded operators that appear naturally in the study of delay equations. He gives necessary and sufficient conditions such that the system of eigenvectors and generalized eigenvectors for operators from this class is complete. As applications he considers examples which include both autonomous and periodic delay equations.
