For an indeterminate Stielijes moment sequence the multiplication operator \(M p(x)=x p(x)\) is positive definite and has self-adjoint extensions. Exactly one of these extensions has the same lower bound as \(M\). the so-called Friedrichs extension. The spectral measure of this extension gives a cer
