Abstract:

Let $\mathcal {A}$ be a nest algebra and ${\mathcal L}at \mathcal {A}$ its invariant projection (or subspace) lattice. In this paper, using order homomorphisms of ${\mathcal L}at \mathcal {A}$, we give necessary and sufficient conditions on bounded linear operators $X$ and $Y$ on a Hilbert space to guarantee the existence of an operator $A$ in a certain $\mathcal {A}$-module such that $AX = Y$.
