COMPACT MULTIPLICATION OPERATORS ON NEST ALGEBRAS

Let N be a nest on a Hilbert space H and Alg N the corresponding nest algebra. We obtain a characterization of the compact and weakly compact multiplication operators defined on nest algebras. This characterization leads to a description of the closed ideal generated by the compact elements of Alg N...

Description
Summary:Let N be a nest on a Hilbert space H and Alg N the corresponding nest algebra. We obtain a characterization of the compact and weakly compact multiplication operators defined on nest algebras. This characterization leads to a description of the closed ideal generated by the compact elements of Alg N. We also show that there is no non-zero weakly compact multiplication operator on Alg N/Alg N ∩ K(H).
