Sums of four and more unit fractions and approximate parametrizations
We prove new upper bounds on the number of representations of rational numbers [Formula: see text] as a sum of four unit fractions, giving five different regions, depending on the size of [Formula: see text] in terms of [Formula: see text]. In particular, we improve the most relevant cases, when [Fo...
