WebThe Gelfand–Naimark Theorem states that an arbitrary C*-algebra A is isometrically *-isomorphic to a C*-algebra of bounded operators on a Hilbert space. There is another version, which states that if X and Y are compact Hausdorff spaces, then they are homeomorphic iff C ( X) and C ( Y) are isomorphic as rings. Are these two related anyway?

In functional analysis, a discipline within mathematics, given a C*-algebra A, the Gelfand–Naimark–Segal construction establishes a correspondence between cyclic *-representations of A and certain linear functionals on A (called states). The correspondence is shown by an explicit construction of the *-representation from the state. It is named for Israel Gelfand, Mark Naimark, and Irving Segal.
