On the sums of non-negative quasi-continuous functions (Q1912657)

The author deals with functions \(f: \mathbb{R}^m\to \mathbb{R}\) (\(\mathbb{R}\) -- the real line). The main result of the paper gives a characterization of functions which are expressible as the sum of at most \(k\) quasi-continuous functions bounded below for each positive integer \(k\).
