Abstract

Let A denote the set of arithmetic functions and ∗ Dirichlet convolution. The paper presents and alternative approach to the study of arithmetic functions by introducing a homomorphism between the subgroup <U, ∗> of the group of units in <A, ∗> and the quotient ring induces through an equivalence relation. The same notion is extended to the case of unitary convolution.
