Abstract

In this article, we continue our study of Baire one functions on a topological space XX, denoted by B1(X)B_1(X) and extend the well known M. H. Stones's theorem from C(X)C(X) to B1(X)B_1(X). Introducing the structure space of B1(X)B_1(X), it is observed that XX may not be embedded inside this structure space. This observation inspired us to build a space M(B1(X))/\mathcal{M}(B_1(X))/\sim, from the structure space of B1(X)B_1(X) and to show that XX is densely embedded in M(B1(X))/\mathcal{M}(B_1(X))/\sim. It is further established that it is a T0T_0-compactification of XX. Such compactification of XX possesses the extension property for continuous functions, though it lacks Hausdorffness in general. Therefore, it is natural to search for condition(s) under which it becomes Hausdorff. In the last section, a set of necessary and sufficient conditions for such compactification to become a Stone-Ceck compatification, is finally arrived at.
