Abstract |
|
A set of subspaces of a Hilbert space is called a nest if it is totally ordered by inclusion. The aim of this paper is to obtain a complete set of unitary invariants for a class of nests satisfying certain conditions. The conditions imposed are a countability condition, (satisfied by all nests of subspaces of a separable Hilbert space), and a simple completeness condition. |
