Embedding normed linear spaces into C(X)

Abstract

It is well known that every (real or complex) normed linear space LL is isometrically embeddable into C(X)C(X) for some compact Hausdorff space XX. Here XX is the closed unit ball of LL^* (the set of all continuous scalar-valued linear mappings on LL) endowed with the weak^* topology, which is compact by the Banach-Alaoglu theorem. We prove that the compact Hausdorff space XX can indeed be chosen to be the Stone-Cech compactification of L{0}L^*\setminus\{0\}, where L{0}L^*\setminus\{0\} is endowed with the supremum norm topology.
