Aimed at graduate students, this textbook provides an accessible and
comprehensive introduction to operator theory. Rather than discuss the
subject in the abstract, this textbook covers the subject through twenty
examples of a wide variety of operators, discussing the norm, spectrum,
commutant, invariant subspaces, and interesting properties of each
operator.
The text is supplemented by over 600 end-of-chapter exercises, designed
to help the reader master the topics covered in the chapter, as well as
providing an opportunity to further explore the vast operator theory
literature. Each chapter also contains well-researched historical facts
which place each chapter within the broader context of the development
of the field as a whole.
