Moreover, if L=K is a separable extension, then equality holds for some extension L0=K. Proof. We sketch the proof for the case L=Kis a nite separable extension. By primitive element theorem we can write L= K( ) for some 2L.

http://mathonline.wikidot.com/kronecker-s-field-extension-theorem 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 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. Specifically we show the following. 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 ...
Web29 de dez. de 2015 · The author has extended the Friedgut–Kalai–Naor theorem to the slice, the subset of the Boolean cube consisting of all vectors with fixed Hamming weight, and extends the theorem further, to the multislice, a multicoloured version of the slice. WebLess briefly: In our abstract algebra class, we were asked to prove the following theorem: Problem: Let $K$ be a finite extension of $F$. Prove that $K$ is a splitting field over $F$ …
