Duals of Anisotropic Hardy Spaces
Shai Dekel
Abstract: In the talk we first review the highly anisotropic Hardy spaces introduce in [1]. We will then discuss a careful approximation argument that is needed when analyzing dual spaces of Hardy spaces [2]. As explained in [3], one cannot assume that a linear functional, uniformly bounded on all atoms, is automatically bounded on spaces that have atomic representations (e.g. Hardy spaces).
