The last example above illustrates a problem which will be of great concern to us in the remainder of this chapter : the problem of finding which formal differential operators and sets of boundary conditions lead to spectral operators .

But , under the condition that the set of boundary conditions C ( US ) = 0 is regular , this has been established above . Thus , to complete the proof , it suffices to show that the set C of boundary conditions C ( Uf ) = 0 , i = 1 ...
