== 「それを忘れて、それを忘れて ==


In [[mathematics]], the '''Gelfand–Naimark theorem''' states that an arbitrary [[C*-algebra]] ''A'' is isometrically *-isomorphic to a C*-algebra of [[bounded operator]]s on a [[Hilbert space]]. This result was proven by [[Israel Gelfand]] and [[Mark Naimark]] in 1943 and was a significant point in the development of the theory of C*-algebras since it established the possibility of considering a C*-algebra as an abstract algebraic entity without reference to particular realizations as an [[operator algebra]].

It suffices to show the map π is [[injective]], since for *-morphisms of C*-algebras injective implies isometric. Let ''x'' be a non-zero element of ''A''.  By the [[Krein extension theorem]] for positive [[linear functional]]s, there is a state ''f'' on ''A'' such that ''f''(''z'') ≥ 0 for all non-negative z in ''A'' and ''f''(&minus;''x''* ''x'') < 0.  Consider the GNS representation π<sub>''f''</sub> with [[cyclic vector]] ξ. Since

The construction of Gelfand–Naimark ''representation'' depends only on the GNS construction and therefore it is meaningful for any [[Banach *-algebra]] ''A'' having an [[approximate identity]]. In general it will not be a [[faithful representation]].  The closure of the image of π(''A'')  will be a C*-algebra of operators called the [[C*-enveloping algebra]] of ''A''.

as ''f'' ranges over pure states of ''A''.   This is a semi-norm, which we refer to as the ''C* semi-norm'' of ''A''. The set '''I''' of elements of ''A'' whose semi-norm is 0 forms a two sided-ideal in ''A'' closed under involution.
