Spherical Carleson conjecture. The estimate

Let $T$ satisfy the full-range sparse domination bound referred to in the source. Let $X$ be a Banach function space such that $M:X\to X$ and $M:X'\to X'$ are bounded. Logarithmic…

Sparse form domination conjecture. The same estimate should also hold after replacing $q_0$ by any $q\in(0,q_0]$.
