Shift Operators,are restrictions of bilateral shifts to certain invariant subspaces. The results of this chapter have much wider applicability than this would suggest however, for, as we shall see, every operator is unitarily equivalent to a multiple of a “part” of the adjoint of a unilateral shift.

Compact Operators, operators have non-trivial invariant subspaces; much more general results are obtained in Chapter 8. We also show that the properties of normality and quasinilpotence for compact operators are determined by their invariant subspaces, and give examples of attainable lattices that are not attainable by compact operators.

Introduction and Preliminaries,Most of this chapter consists of certain basic definitions and results that will be required later. With the exception of Section 0.4 the results are all very well-known. The reader may wish to use the other sections merely for reference regarding notation.

Algebras Associated with Invariant Subspaces,In this chapter we consider subalgebras Q of ℬ(ℋ) which are not transitive, and establish certain relations between .Q and various properties of Q. We begin with the following problem.
