WebHilbert's theorem was first treated by David Hilbertin "Über Flächen von konstanter Krümmung" (Trans. Amer. Math. Soc.2 (1901), 87–99). A different proof was given shortly after by E.

Originally, Hilbert's Theorem 90 is the following number theoretical result [5]: Given a cyclic Galois extension K ⊂ L of number fields, each y ∈ L× of norm N ( y )=1 is of the form y = x / xσ for some x ∈ K× and a given generator σ ∈ G of the Galois group.

WebIn cohomological language, Hilbert's Theorem 90 is the statement that $H^1(Gal(L/K), L^{\times}) = 0$ for any finite Galois extension of fields $L/K$. To recover the statement … WebNow Hilbert’s Theorem 90 claims that the kernel of the normal map should consist of elements of the form ˙(y)=y. Since ˙(y)=y= yq=y= yq 1 and (q 1) jjL j, kerNL K should have order jL j=(q 1) = (qr 1)=(q 1), which is just what we showed. 3.
