Brevig–Ortega-Cerdà–Seip–Zhao conjecture on contractive Hardy–Dirichlet inclusions

About 5 years old · traced to

Let p>2p>2, let D\mathbb{D} be the unit disk, and let ff be analytic in D\mathbb{D}. Denote by ∥f∥Hp\|f\|_{H^p} the Hardy-space norm and by ∥f∥Dp/2\|f\|_{D_{p/2}} the norm of the corresponding Dirichlet space. Brevig–Ortega-Cerdà–Seip–Zhao conjecture. The inequality

∥f∥Hp≤∥f∥Dp2\| f \|_{H^p} \leq \| f \|_{D_{\frac{p}{2}}}

holds for all such ff. This conjecture concerns contractive inclusions between Hardy and Dirichlet spaces; the supplied source does not state whether it has been resolved.
