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.

If the Weyl tensor is non-zero, we disclose new equations in the system ɛ, which are differential corollaries of ord ≤ k, and so we change the system by adding them. The new system is Hilbert's Theorem 90 then states that every such element a of norm one can be written as = + = + +, where = + is as in the conclusion of the theorem, and c and d are both integers.
