To illustrate more clearly the relationship between Theorem 6 and the well known
result for self adjoint operators , we observe that a self adjoint operator or , more
generally , a normal operator in AP is a spectral operator . For if A is a normal ...

where h is Hilbert ' s singular integral ( 34 ) , is an operator in A which is not self
adjoint , and not normal unless il a - b ) is self adjoint but is , for many choices of a
and b , a spectral operator . To see this , equation ( 35 ) shows that the condition
