Web10 de set. de 2024 · When α n = ∑ i ∈ S κ i for some S ⊆ [ℓ], it is natural to conjecture that the sets of the form A = {u: u j ∈ S} minimize the expansion, and this is indeed the case. Using our FKN theorem, we are able to show a stability version of this result: if a set of size α n has almost minimal expansion, then it is close to a set with minimal ... Web•Hypercontractivity and a quantum FKN theorem. The Friedgut-Kalai-Naor (FKN) theorem [FKN02] states that boolean functions whose Fourier transform is concentrated on the ﬁrst level approximately depend on a single variable. We prove a quantum analogue of this statement. In order to obtain this result, we state and darling in the franxx cdaWebIn this, the first part of a two-part paper, we establish a theorem concerning the entropy of a certain sequence of binary random variables. In the sequel we will apply this result to the solution of three problems in multi-user communication, two of which have been open for some time.

"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. " - On some extensions of the fkn theorem

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 ...
