Abstract

It has recently been established that any Baire class one function ƒ : [0, 1] → ℝ can be represented as the pointwise limit of a sequence of polygonal functions whose vertices lie on the graph of ƒ. Here we investigate the subclass of Baire class one functions having the additional property that for every dense subset D of [0, 1], the first coordinates of the vertices of the polygonal functions can be chosen from D.
