Hilbert's theorem 90
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). http://www.southerndays.info/Starling/Adam_Starling_notes.html

Fortu-nately, we have an alternative characterization of Hilbert-Schmidt norm (and thus Hilbert-Schmidt operators) via Hilbert bases, which is easier to use.

WebHilbert's theorem was first treated by David Hilbert in "Über Flächen von konstanter Krümmung" (Trans. Amer. Math. Soc. 2 (1901), 87–99). A different proof was given shortly after by E. Holmgren in "Sur les surfaces à courbure constante négative" (1902). A far-leading generalization was obtained by Nikolai Efimov in 1975.
