Some Unsolved Problems,e more tractable than the general cases, and we also consider some related questions. Our list of unsolved problems is representative rather than exhaustive; a number of other problemswill no doubt occur to the reader.

Analytic Functions of Operators,ontaining .(.). The functional calculus which we shall develop is not as rich as the functional calculus for normal operators; nonetheless it has important applications to the study of invariant subspaces. It also has many other important applications which we shall not discuss; (e.g., see Proposition 2.3).

Existence of Invariant and Hyperinvariant Subspaces,n particular, we obtain the result that parts of the adjoints of finite-multiplicity unilateral shifts have invariant subspaces, thereby proving the factorization theorem for isometry-valued analytic functions alluded to in Section 3.6.
