Webthe following key result about polynomial rings, known as the Hilbert Basis Theorem: Theorem 1.1. Let Rbe a Noetherian ring. Then R[X] is Noetherian. Proof. The following proof is due to Emmy Noether, and is a vast simpli- cation of Hilbert’s original proof. Let Ibe an ideal of R[X]; we want to show that Iis nitely generated. Let P(X) = b 0 ... 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. Let Kbe the splitting eld over Q(!), !a primitive cube root of unity, of the polynomial x3 3x+1.

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. Holmgren in "Sur les surfaces à courbure constante négative" (1902). A far-leading generalization was obtained by Nikolai Efimovin 1975.

WebHilbert space was found to be very useful for the formu-lations in quantum mechanics (Prugovecki,1982). After the initial works on Hilbert space by Hilbert and Schmidt (Hilbert,1904;Schmidt,1908), James Mercer improved Hilbert’s work and proposed his theorem in 1909 (Mer-cer,1909) which was named the Mercer’s theorem later.
