WebLater the conditions under which an operator is similar to a part of a weighted shift were studied. Some Rota type models for operators using weighted shifts were obtained in [6] and [12]. It is natural to ask when an operator is unitarily equivalent to a part of a weighted shift. This question was first studied by Agler [1], [2] who proved a Webof weighted shifts in the paper [12] to general weighted sequence spaces. The structure of this paper is as follows: Section 2 gives some de nitions and propositions. The disjoint …
