If a generalized sequence of projections in a o - complete Boolean algebra of
projections in a B - space converges weakly to a projection , then it converges
strongly . PROOF . In view of Lemma 23 , the proof may be restricted to the case ...

Let rn be the distance from the eigenvalue in to the other points on the spectrum
of T , so that rn > 0 , while , of course , the sequence { rn } , like the sequence in ,
is bounded . Let R be the closed , densely defined , unbounded operator in X ...
