Abstract:A collection begin{math}mathcal{D}end{math} of subsets of a space is minimal if each element of begin{math}mathcal{D}end{math} contains a point which is not contained in any other element of begin{math}mathcal{D}end{math}. A base of a topological space is begin{math}sigmaend{math}-minimal if it can be written as a union of countably many minimal collections. We will construct a compact linearly ordered space begin{math}Xend{math} satisfying that begin{math}Xend{math} is not metrizable and every subspace of begin{math}Xend{math} has a begin{math}sigmaend{math}-minimal base for its relative topology. This answers a problem of Bennett and Lutzer in the negative.

Keywords:(sigma)-minimal base   metrizable   linearly ordered topological space   special Aronszajn tree   quasi-developable
