The theory of Lp spaces for outer measures, or outer Lp spaces, was developed by Do and Thiele to encode the proof of boundedness of certain multilinear operators in a streamlined argument. Accordingly to this purpose, the theory was developed in the direction of the real interpolation features of these spaces, such as versions of Hölder´s inequality and Marcinkiewicz interpolation, while other questions remained untouched.

For example, the outer Lp spaces are defined by quasi-norms generalizing the classical mixed Lp norms on sets with a Cartesian product structure; it is then natural to ask whether in arbitrary settings the outer Lp quasi-norms are equivalent to norms. In this talk, we will answer this question, with a particular focus on a specific setting on the upper half space Rd - (0, ∞). This will allow us to clarify the relation between outer Lp spaces and tent spaces.
