Abstract
We use a Ramsey-theoretic argument to obtain the first
lower bounds for approximations over ¥§¦ by nonlinear
polynomials:
¨ A degree-© polynomial over ¥ ¦ (

odd) must
differ from the parity function on at least a
© ©!#"%$'&%()10 fraction of all points in the
Boolean 2 -cube.
¨ A degree-354 6 polynomial over ¥§¦ (
