    Littlewood-Offord Bounds on Permutations

    Published:Dec 25, 2025 20:32
    1 min read
    ArXiv

    Analysis

    This paper investigates anti-concentration phenomena in the context of the symmetric group, a departure from the typical product space setting. It focuses on the random sum of weighted vectors permuted by a random permutation. The paper's significance lies in its novel approach to anti-concentration, providing new bounds and structural characterizations, and answering an open question. The applications to permutation polynomials and other results strengthen existing knowledge in the field.
    Reference

    “The paper establishes a near-optimal structural characterization of the vectors w and v under the assumption that the concentration probability is polynomially large. It also shows that if both w and v have distinct entries, then sup_x P(S_π=x) ≤ n^{-5/2+o(1)}.”
