Abstract

we prove that if XX is a locally compact σ\sigma-compact space then on its quotient, γ(X)\gamma(X) say, determined by the algebra of all real valued bounded continuous functions on XX, the quotient topology and the completely regular topology defined by this algebra are equal. It follows from this that if XX is second countable locally compact then γ(X)\gamma(X) is second countable locally compact Hausdorff if and only if it is first countable. The interest in these results originated in papers of R. J. Archbold, and S. Echterhoff and D. P. Williams where the primitive ideal space of a CC^*-algebra was considered.
