Hilbert's theorem 90

WebSep 7, 2002 · Hilbert's Theorem 90 and algebraic spaces. 1. Introduction. 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.
