Gelfand and Naimark's paper on the Gelfand–Naimark theorem was published in 1943. Segal recognized the construction that was implicit in this work and presented it in sharpened form. In his paper of 1947 Segal showed that it is sufficient, for any physical system that can be described by an algebra of operators on a Hilbert space, to consider the irreducible representations of a C*-algebra. In quantum theory this means that the C*-algebra is generated b… WebJun 3, 2015 · 1 Answer.

WebThe theorem is proved in Section 2 as Theorem 2.3. The proof uses the fact that, for the rings in Theorem 1, all ﬁnite R-modules have rational Poincar´e series which share an explicitly known denominator: this is due to Jacobsson, Kustin, Miller [13], [14], [15].
