C.6 Adjoints for Operators on a Hilbert Space
... By Theorem C.50, since we are dealing with complex Hilbert spaces, all positive and positive definite operators are self-adjoint. When dealing with real Hilbert spaces, the assumption of self-adjointness should be added in the definition of positive and positive definite operators. The next exercise ...
