Abstract

A topological space XX is Baire if the intersection of any sequence of open dense subsets of XX is dense in XX. Let Cp(X,[0,1])C_p(X,[0,1]) denote the space of all continuous [0,1][0,1]-valued functions on a Tychonoff space XX with the topology of pointwise convergence. In this paper, we have obtained a characterization when the function space Cp(X,[0,1])C_p(X,[0,1]) is Baire for a Tychonoff space XX all separable closed subsets of which are CC-embedded. In particular, this characterization is true for normal spaces and, hence, for metrizable spaces. Moreover, we obtained that the space Cp(X,[0,1])C_p(X,[0,1]) is Baire, if and only if, the space Cp(X,K)Cp(X,K) is Baire for a Peano continuum KK.
