Representations of positive integers
Владимир Григорьевич Чирский, V. Yu. Matveev · Moscow University Mathematics Bulletin · 2013
The problem of representing integers as sums of terms of certain type is actual in number theory and its applications. We are interested in the average length of these expansions and the required number of auxiliary calculations. The paper deals with DBNS, chains, and the polyadic (factorial) expansions of positive integers.
