  1. A variation norm Carleson theorem.

    Authors: Terence Tao, Richard Oberlin, Andreas Seeger, Christoph Thiele, James Wright
    Subjects: Classical Analysis and ODEs
    Abstract

    We strengthen the Carleson-Hunt theorem by proving $L^p$ estimates for the
    $r$-variation of the partial sum operators for Fourier series and integrals,
    for $p>\max\{r',2\}$. Four appendices are concerned with transference, a
    variation norm Menshov-Paley-Zygmund theorem, and applications to nonlinear
    Fourier transforms and ergodic theory.
