Abstract

Associated with every separable Hilbert space H\mathcal{H} and a given localized frame, there exists a natural test function Banach space H1\mathcal{H}^1 and a Banach distribution space H\mathcal{H}^{\infty} so that H1HH\mathcal{H}^1 \subset \mathcal{H} \subset \mathcal{H}^{\infty}. In this article we close some gaps in the literature and rigorously introduce the space H\mathcal{H}^{\infty} and its weighted variants Hw\mathcal{H}_w^{\infty} in a slightly more general setting and discuss some of their properties. In particular, we compare the underlying weak^*- with the norm topology associated with Hw\mathcal{H}_w^{\infty} and show that (Hw,Hw)(\mathcal{H}_w^{\infty}, \Vert \cdot \Vert_{\mathcal{H}_w^{\infty}}) is a Banach space.
