Definition: Multiplicative Functions

An arithmetic function \(\beta\) with at least one \(m\in\mathbb N\) with \(\beta(m)\neq 0\) is called:

  1. multiplicative, \(\beta(mn)=\beta(m)\beta(n)\) for all relatively prime \(m,n\in\mathbb N\),
  2. completely multiplicative, if \(\beta(mn)=\beta(m)\beta(n)\) for all \(m,n\in\mathbb N\).
