In Chapter XV we try to stress most of the basic elementary properties of spectral operators that distinguish them from other operators . These properties assume a variety of forms not immediately apparent from the definition of a ...

Statement of the Problem In the preceding chapter we studied the properties of bounded spectral operators , that is , operators which have a countably additive resolution of the identity defined on the field of Borel sets .
