Your link to an answer went to a question, so I assumed you meant the sole answer, and edited accordingly. I hope that was correct. \\ @MichaelHardy, thanks for adding \tags in your edit! If you combine those with \labels, then one can \eqref them. I edited accordingly In fact, they are global labels per page, so one can \eqref even in an answer or comment (as to \eqref{1} and \eqref{2}).

| Jul 19, 2023 at 0:42 | comment | added | Terry Tao | There exists a choice of $t$ such that $|Rf(x)| \geq \frac{1}{2} Sf(x)$ (say) for all $x$: one basically chooses $t(x)$ to nearly maximize $|T f(t,x)|$, conceding a factor of 2 so that we don't have to worry about whether the supremum is attained. [There is a small technicality in ensuring that $t$ can be chosen measurably.] This technique is often referred to as "linearizing a maximal operator". I believe it is discussed in Stein's "Harmonic analysis" in the section on maximal operators, though I do not have it handy at present; maybe others can supply more precise references. | |
