Abstract
In [1] Krassimir Atanassov has introduced the arithmetic function RF(n) defined by RF(1) = 1 and RF(n) = q1α1−1q2α2−1… qkαk−1 whenever n = q1α1 q2α2… qkαk, where q1, …, qk are pairwise different prime numbers and we have α1…αk ≥ 1. The function RF(n) is called the restrictive factor. In the present paper we denote it simply by R(n).
