A note on generalized mobius (s-functions

In [1] the concept of a conjugate pair of sets of positive integers is introduced. Briefly, if Z denotés the set of positive integers and P and Q denote non-empty subsets of Z such that: if n1 (pertenece a) Z, n2 (pertenece a) Z, (n1,n2) = 1, then (1) n = n1n2 (pertenece a) P(resp. Q) n1 (pe...
