Hilbert 90 theorem

WebHilbert's theorem may refer to: . Hilbert's theorem (differential geometry), stating there exists no complete regular surface of constant negative gaussian curvature immersed in Hilbert's Theorem 90, an important result on cyclic extensions of fields that leads to Kummer theory; Hilbert's basis theorem, in commutative algebra, stating every ideal in the … WebHilbert's Theorem 90 Let L/K be a finite Galois extension with Galois group G, and let ZC7 be the group ring. If a £ L* and g £ G, we write ag instead of g(a). Since a" is the rath power of a as usual, in this way L* becomes a right ZG-module in the obvious way. For example, if r = 3g + 5 G ZC7, then of = (a$)g(as).
