WebApr 14, 2016 · We know that if L / k is a finite Galois extension then H 1 ( G a l ( L / k), L ∗) = 0 (Hilbert's theorem 90). However I would like to know if there is some generalized version involving some field extension M / L such that H 1 ( G a l ( L / k), M ∗) = 0? Here note that L and M are not the same as in the usual version H 1 ( G a l ( L / k), L ∗) =0. 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 ...
