PATODIA, Harish  and  SAIKIA, Helen K.. Near-Zumkeller numbers. Proyecciones (Antofagasta) [online]. 2022, vol.41, n.3, pp.765-776. ISSN 0716-0917.

A positive integer n is called a Zumkeller number if the set of all the positive divisors of n can be partitioned into two disjoint subsets, each summing to σ(n)/2. In this paper, Generalizing further, near-Zumkeller numbers and k-near-Zumkeller numbers are defined and also some results concerning these numbers are established. Relations of these numbers with practical numbers are also studied in this paper.

Keywords : perfect numbers; Zumkeller numbers; practical numbers; fermat primes.
