%0 Journal Article %T On the dual space C0*(S, X) %A L. Meziani %J ACTA MATHEMATICA UNIVERSITATIS COMENIANAE %D 2012 %I Acta Mathematica Universitatis Comenianae %X . Let S be a locally compact Hausdorff space and let us consider the space C0(S, X) of continuous functions vanishing at infinity, from S into the Banach space X. A theorem of I. Singer, settled for S compact, states that the topological dual C0*(S, X) is isometrically isomorphic to the Banach space r¦Òbv(S, X*) of all regular vector measures of bounded variation on S, with values in the strong dual X*. Using the Riesz-Kakutani theorem and some routine topological arguments, we propose a constructive detailed proof which is, as far as we know, different from that supplied elsewhere. %K vector-valued functions %K bounded functionals %K vector measures. %U http://www.emis.de/journals/AMUC/_vol-78/_no_1/_meziani/meziani.html
