Rapidly Convergent Series of the Divisors Functions
arXiv:1407.7439
Abstract
This note gives a few rapidly convergent series representations of the sums of divisors functions. These series have various applications such as exact evaluations of some power series, computing estimates and proving the existence results of some special values of the sums of divisors functions.
