Webhas extended the theorem to the slice, the subset of the Boolean cube consisting of all vectors with ﬁxed Hamming weight. We extend the theorem further, to the multislice, a multicoloured version of the slice. As an application, we prove a stability version of the edge-isoperimetric inequality for settings of WebIn other words, the answer depends either on the image of some point i or on the inverse image of some point j. The two options correspond to the anti-isomorphism π %→ π−1 of S n. The symmetric group corresponds, in some sense, to µ p for p = 1/n.

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
