Local embedding inequality for non-even exponents greater than two
Determine whether the local embedding inequality \(\int_0^1 |f(1/2+it)|^q\,dt\lesssim \|f\|_{\mathscr H^q}^q\) holds for every \(q>2\) with \(q\notin 2\mathbb N\), for Hardy-space functions of Dirichlet series.
References
The inequality is still open for q > 2, q \notin 2\mathbb{N}.
