Abstract

A topological space X is Baire if the intersection of any sequence of open dense subsets of X is dense in X. In this paper, we establish that the property (κ) for a Tychonoff space X is equivalent to Baireness of B1(X), and hence, the Banakh property for Cp(X) is equivalent to meagerness of B1(X). Thus, we obtain one characteristic of the Banakh property for Cp(X) through the property of the space X.
