Additive transform of an arithmetic function : Part I
The Additive Transform of an arithmetic function represents a novel approach to examining the interplay between multiplicative arithmetic function and additive functions. This transform concept introduces a method to systematically generate new arithmetic functions by combining the values of an existing function under an additive operation. The resulting framework not only extends our understanding of classical arithmetic functions but also provides a versatile tool for exploring additive relationships within the realm of number theory. In this article, we present the fundamental principles of the Additive Transform and illustrate its application through various examples, shedding light on its potential implications for diverse mathematical domains. For all positive integer $n$. a motivation for the present study is to give a new concept named the Additive transform of an arithmetic function $f$ when $f$ equals some special arithmetic functions, that new concept can help us to prove many results like : \begin{equation} \big(μ*f.Id\big)(n) =φ(n)f(n)+φ(n) \sum \limits_{p^α||n} \frac{f(p^α)-f(p^{α-1})}{p-1} \end{equation} where $f$ is an additive function.
