Abstract

Let P be a polynomial of degree d in independent Bernoulli random variables which has zero mean and unit variance. The Bonami hypercontractivity bound implies that the probability that | P| > t decays exponentially in t² ^∕ ^d. Confirming a conjecture of Keller and Klein, we prove a local version of this bound, providing an upper bound on the difference between the e⁻ ^r and the e⁻ ^r ⁻ ¹ quantiles of P.
