Approximations by Darboux functions in the Baire one class

Robert Menkyna, Ľubomír Mydielka

Abstract


In the paper [7], Z. Zahorski designed a way of constructing
the real semi-continuous functions. %During this session, in the presented
Throughout the present paper,  it is shown that a modification of  Zahorski's approach is
usefull for approximation of a Baire one function by a Darboux Baire one function.
