    4 = 2 × 2, or the Power of Even Integers in Fourier Analysis
    (Oberwolfach : Mathematisches Forschungsinstitut Oberwolfach gGmbH, 2023) Negro, Giuseppe; Oliveira e Silva, Diogo
    We describe how simple observations related to vectors of length 1 recently led to the proof of an important mathematical fact: the sharp Stein–Tomas inequality from Fourier restriction theory, a pillar of modern harmonic analysis with surprising applications to number theory and geometric measure theory.
