Divisor sum identities
The purpose of this page is to catalog new, interesting, and useful identities related to number-theoretic divisor sums, i.e., sums of an arithmetic function over the divisors of a natural number n {\displaystyle n} , or equivalently the Dirichlet convolution of an arithmetic function f ( n ) {\displaystyle f(n)} with one:
