"WebThis theorem is sharp, up to the universal constant C. In the proof the inequality (1) has been used. However, in the non-symmetric case one can ask for a better bound involving bias parameter α. In this note we use inequality (2) to prove such an extension of the FKN Theorem. Namely, we have Theorem 2. Let f = P " - On some extensions of the fkn theorem
