On theorems of Pu & Pu and Grande

Abstract: Given a finite family of cliquish functions, $\A$, we can find a Lebesgue function $\alpha$ such that $f+ \alpha$ is Darboux and quasi-continuous for every $f \in\A$. This theorem is a generalization both of the theorem by H. W. Pu & H. H. Pu and of the theorem by Z. Grande.

Keywords: quasi-continuous function, cliquish function, Lebesgue function
