A major challenge in complexity theory is to explicitly construct functions that have small correlation with low-degree polynomials over F2. We introduce a new technique to prove such correlation bounds with F2polynomials. Using this technique, we bound the correlation of an XOR of Majorities with constant degree polynomials. In fact, we prove a more general XOR lemma that extends to arbitrary resilient functions. We conjecture that the technique generalizes to higher degree polynomials as well.A key ingredient in our new approach is a structural result about the Fourier spectrum of low degree polynomials over F2. We show that for anyn-variate polynomialpover F2of degree at mostd, there is a small setS⊂ [n] of variables, such that almost all of the Fourier mass ofplies on Fourier coefficients that intersect withS. In fact our result is more general, and finds such a setSfor any low-dimensional subspace of polynomials. This generality is crucial in deriving the new XOR lemmas.
