§27.17 Other Applications
Reed et al. (1990, pp. 458–470) describes a number-theoretic approach to Fourier analysis (called the arithmetic Fourier transform) that uses the Möbius inversion (27.5.7) to increase efficiency in computing coefficients of Fourier series. …
2: 27.5 Inversion Formulas
which, in turn, is the basis for the Möbius inversion formula relating sums over divisors: … Special cases of Möbius inversion pairs are: … Other types of Möbius inversion formulas include: … For a general theory of Möbius inversion with applications to combinatorial theory see Rota (1964).
3: 27.6 Divisor Sums
Generating functions, Euler products, and Möbius inversion are used to evaluate many sums extended over divisors. …
