Soient B un espace de Banach et ℒ(B) l'algèbre des opérateurs bornés sur B. On dit qu'un sous-espace fermé E de B est invariant pour l'opérateur T ∈ ℒ(B) lorsque TE ⊂ E et qu'il est non trivial si {0} EB. Le sous-espace E est dit hyper-invariant pour T s'il est invariant pour tout opérateur qui commute avec T.
