Abstract
Let A be a stable, σ-unital, continuous C 0(X)-algebra with surjective base map φ :\(\mathrm{Prim}(A)\;\rightarrow X\), where Prim(A) is the primitive ideal space of the C*-algebra A. Suppose that \(\phi^{-1}(x)\) is contained in a limit set in Prim(A) for each \(x \in X\) (so that A is quasi-standard). Let CR(X) be the ring of continuous real-valued functions on X. It is shown that there is a homeomorphism between the space of minimal prime ideals of CR(X) and the space MinPrimal(M(A)) of minimal closed primal ideals of the multiplier algebra M(A). If A is separable then MinPrimal(M(A)) is compact and extremally disconnected but if \(X = \beta \bf{N} \setminus \bf{N}\) then MinPrimal(M(A)) is nowhere locally compact.
