    Abstract: For h=3 or 4, Egyptian decompositions into h unit fractions, like 2/D = 1 /D1 +... +1 /Dh, were given by using (h-1) divisors (di) of D1. This ancient modus operandi, well recognized today, provides Di=DD1/di for i greater than 1. Decompositions selected (depending on di) have generally been studied by modern researchers through the intrinsic featu... Show More
