Hey younghorsey.

What is v(d)? Is this some kind of special analytic number theory function? - Jul 24th 2013, 07:26 AMyounghorseyRe: Sum of Positive Divisors Function
Hey chiro.

I don't know enough number theory to help you on this one.

What I would recommend you do is collect as many identities as possible and put them all in the one place: this will help you see the connections a lot quicker and should help you solve your problem quicker than say a less structured approach.

If you have all the identities and theorems on a few pages the connections should pop out. - Jul 26th 2013, 02:25 PMjohngRe: Sum of Positive Divisors Function
Hi,

The attachment provides a proof. I've left the proofs of several relevant facts to you.
