Talk:Divisor function

I would never use the phrase "divisor function" to refer to the very general $\sigma_k(n)$ -- I strongly suggest that the article be rewritten to emphasize the function $d(n)$ first, and then to later comment on $\sigma_k(n)$ as a generalization. Perhaps the main article for $\sigma_k(n)$ could be a separate page, e.g., "sum of divisors function" (except that such a page should properly belong just to $\sigma(n)$). --JBL 16:58, 21 July 2009 (UTC)
