Talk:Divisor function

From AoPSWiki

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)
