“The relationship between Z^0 to C_0, B_0, and H_0 is an example of a
general principle which we have encountered: the kernel of the
adjoint of a linear transformation is both the annihilator space of
the image of the transformation and also the dual space of the
quotient of the space of which the image is a subspace by the image
