Of course it is not clear to begin with that a countably additive resolution of the
identity defined on the Borel sets of the plane is uniquely determined by the
spectral operator T . This is the case , but until it is proved we refer to any such
spectral ...

In the examples of Theorems 19 and 21 we did not appeal to the general theory ,
as it was clear from the form of exp t that T ( t ) o was differentiable for t > 0 and
an arbitrary q in H ” . It is even clear that the nth order derivative T ' ( n ) ( t ) exists

It is clear that the union of intervals of constancy is open . ... It is clear from the
second expression for yn that it is closed , and it follows from ( G ) that every point
in y is in one of the sets Yn . Thus , by the Baire category theorem ( cf . 1 . 6 .
