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.
