Abstract: The cone of nonnegative extended valued normal forms, defined on the nonnegative bounded symmetric operators in a Hilbert space, is discussed in connection with generalising a known inequality to the unbounded case.

The cone of normal forms seems to offer a possibility for seeing unbounded operators in a more general perspective.
