Segal theorem
WebJun 3, 2015 · Personally, I don't consider the Stone Representation Theorem and the GNS-construction to be directly related. However, the former is closely related to the Gelfand representation, which in a way is the commutative version of the Gelfand-Naimark theorem.(Yes, a lot of theorems in the study of Banach algebras are named after Gelfand.)

It also contains multiple proofs of several central results, and it has a minor historical perspective. Key Features Readership Table of Contents Product details About the Author Ratings and Reviews 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…

Furthermore, this isomorphism is covariant for proper maps between Deligne …
WebMay 1, 1973 · A fascinating feature of Segal algebras is that all of them inherit some important properties from L\G) and yet all of them fail to inherit others.
