... given by ( 9 ) and the domain of A consists precisely of those p for which the limit in ( 9 ) exists . Our next concern will be with the question of the existence of a resolution of the identity for A. This leads us to formulate the ...

... given , one attempts to find an operator U such that T + K = U¬1TU , in this way reducing the spectral theory of T + K to that of T. We shall see that this idea can be applied with success to a wide variety of operators and , in ...
