COMMUTANTS AND DOUBLE COMMUTANTS OF REFLEXIVE ALGEBRAS

open access: yesKyushu Journal of Mathematics, 1996
The author studies the commutant and the double commutant of the algebra \(\text{alg }{\mathcal L}\) of all bounded operators on a Banach space \(X\) leaving invariant each member of a lattice \({\mathcal L}\) of subspaces of \(X\). For example, he proves that when \({\mathcal L}\) is the pentagon subspace lattice, then the only operators commuting ...
