我们证明了Khot和Moshkovitz猜想的端点情况与唯一对策猜想有关,误差较小。Letn≥2。假设n维欧几里得空间的子集Ω满足- Ω = Ωcand Ω +v= Ωc(直到测量零集)对于每个标准基向量。对于任意和任意q≥1,令和令。对于任意x∈∂Ω,让N(x)表示外部法向量,使得‖N(x)‖2= 1。让。我们的主要结果表明,在所有这些子集中,b具有最小的高斯表面积Ω,误差较小:特别是,标准论证将这些结果扩展到噪声稳定性的相应弱不等式。除去因子6 × 10−9将证明Khot - Moshkovitz猜想的端点情况。最后,我们证明了Khot和Moshkovitz猜想的欧几里得类似。Khot和Moshkovitz的完整猜想为唯一博弈猜想的真实性提供了强有力的证据,唯一博弈猜想是理论计算机科学中的一个核心猜想,与P对NP问题密切相关。因此,我们的结果也为唯一对策猜想的真实性提供了证据。然而,本文并没有证明唯一对策猜想的任何情况。
We prove the endpoint case of a conjecture of Khot and Moshkovitz related to the unique games conjecture, less a small error. Letn≥ 2. Suppose a subset Ω ofn‐dimensional Euclidean space satisfies −Ω = Ωcand Ω +v= Ωc(up to measure zero sets) for every standard basis vector . For any and for anyq≥ 1, let and let . For anyx∈∂Ω, letN(x) denote the exterior normal vector atxsuch that ‖N(x)‖2= 1. Let . Our main result shows thatBhas the smallest Gaussian surface area among all such subsets Ω, less a small error: In particular, Standard arguments extend these results to a corresponding weak inequality for noise stability. Removing the factor 6 × 10−9would prove the endpoint case of the Khot‐Moshkovitz conjecture. Lastly, we prove a Euclidean analogue of the Khot and Moshkovitz conjecture. The full conjecture of Khot and Moshkovitz provides strong evidence for the truth of the unique games conjecture, a central conjecture in theoretical computer science that is closely related to the P versus NP problem. So, our results also provide evidence for the truth of the unique games conjecture. Nevertheless, this paper does not prove any case of the unique games conjecture.
