Abstract:Let X be a nonempty topological space, C(X)F be the set of all real-valued
functions on X which are discontinuous at most on a finite set and B1(X) be
the ring of all real-valued Baire one functions on X. We show that any
member of B1(X) is a zero divisor or a unit. We give an algebraic
characterization of X when for every p ? X, there exists f ? B1(X) such that
{p} = f ?1(0) and we give some topological characterizations of minimal
ideals, essential ideals and socle of B1(X). Some relations … Show more
