The following results are proved: (i) if , and is a sectorial operator, then the set is bounded; (ii) the same set of operators is R-bounded if is R-sectorial.
Si dimostra che: (i) se , e è un operatore settoriale, allora l'insieme è limitato; (ii) che lo stesso insieme di operatori è R-limitato se è R-settoriale.
