Arithmetic Functions and Operators


Vichian Laohakosola, Nittiya Pabhapoteb,* and Nalinee Wechwiriyakulb


ABSTRACT: Basic results about arithmetic functions and their major operations, namely, valuation, derivation and operators, are collected. The logarithmic and related operators, introduced and applied in 1968 by D Rearick to establish isomorphisms among various groups of real-valued arithmetic functions are extended to complex-valued arithmetic functions along the original lines suggested by him.
