On some representations of a.e. continuous functions. (English) Zbl 0851.26003

Summary: It is proved that the following conditions are equivalent:
(a) \(f\) is an almost everywhere continuous function.
(b) \(f = g + h\), where \(g,h\) are strongly quasi-continuous.
(c) \(f = c + gh\), where \(c \in \mathbb{R}\) and \(g,h\) are strongly quasi-continuous.
