Relation between divisor functions
Does anybody know anything about the relation between sigma(n) and d(n) and about sigma(n)/d(n)?

Are you looking for the normal order, or the average order? |

I thought the question was clear enough. I'm asking some general informations about the relation between these 2 functions. For instance, sigma(n)/d(n). I'd be interested in both the average order and the normal order.

The normal order doesn't exist for d(n). This is what makes your question less than trivial. Hardy & Wright has an excellent discussion of your questions. |
