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).

To observe the use of Hilbert 90-type theorems in the partially published work of Markus Rost and Voevodsky on the Bloch-Kato conjecture, see [11] and [12]. For further original sources on Hilbert 90 and its cohomological generalization see Ernst 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.
