Factorization in Haar system Hardy spaces

Richard Lechner, Thomas Speckhofer

A Haar system Hardy space is the completion of the linear span of the Haar system $(h_{I})_{I}$ , either under a rearrangement-invariant norm $∥ \cdot ∥$ or under the associated square…

Multipliers on bi-parameter Haar system Hardy spaces

Richard Lechner, Pavlos Motakis, Paul F. X. Müller +1

Let $(h_{I})$ denote the standard Haar system on $[0, 1]$ , indexed by $I \in D$ , the set of dyadic intervals and $h_{I} \otimes h_{J}$ denote the tensor product $(s,t)\mapsto h_I(s…
