Abstract
Suppose that H is a complex Hilbert space and that ā¬(H) denotes the bounded linear operators on H. We show that every abelian, amenable operator algebra is similar to a Cā-algebra. We do this by showing that if šāā¬(H) is an abelian algebra with the property that given any bounded representation Ļ±:šāā¬(HĻ±) of š on a Hilbert space HĻ±, every invariant subspace of Ļ±(š) is topologically complemented by another invariant subspace of Ļ±(š), then š is similar to an abelian Cā-algebra.
