Description: Define the adjoint of a Hilbert space operator (if it exists). The domain of is the set of all adjoint operators. Definition of adjoint in [Kalmbach2] p. 8. Unlike Kalmbach (and most authors), we do not demand that the operator be linear, but instead show (in adjbdln 28942) that the adjoint exists for a bounded linear operator.
