WebIn this note we consider Boolean functions defined on the discrete cube {−γ,γ−1}n equipped with a product probability measure μ⊗n, where μ=βδ−γ+αδγ−1 and γ=√α/β. We prove that if the spectrum of such a function is concentrated on the first two Fourier levels, then the function is close to a certain function of one variable.

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. For this reason, we expect the FKN theorem to exhibit behavior similar to the very biased ... WebHence, the statement follows from the Kato–Rellich theorem ([42, Theorem X.12]). 2.2. Feynman–Kac–Nelson Formula In this section, we move to a probabilistic description of the spin boson model. Except for Lemma 2.2, all statements are proved in Sect. 3.1. The spin part can be described by a jump process, which we construct here explicitly.
