Textbook 1998Latest edition reading along with giving some comments on who proved what and when. In addition, following each chapter is a large number of problems of varying difficulty. This new edition will appeal to a new generation of students seeking an introduction to operator theory.

The most important geometrical property absent in general Banach spaces is a notion of perpendicularity or orthogonality.

Operators on Hilbert Space and C*-Algebras,s. Such is also the case in the study of Hilbert spaces. In the remainder of the book we shall be mainly concerned with bounded linear transformations acting on Hilbert spaces. Despite the importance of certain classes of unbounded linear transformations, we consider them only in the problems.
