Exceptional set carleson

exceptional_set_carleson'

Plain-language statement

For a continuous, $2\pi$ -periodic function $f$ and any $\delta,\varepsilon>0$ , there is an index $N_0$ such that the set of $x\in(0,2\pi]$ for which $\sup_{N>N_0}\lVert f(x)-S_Nf(x)\rVert$ exceeds $\delta$ has measure at most $\varepsilon$ .
