On: "Embarrassing" open problems in maths

[JoeAltmaier]

Say it this way then: why that particular equation? Something must have prompted the formulation of the question - what was it?

[hyperbovine → JoeAltmaier]

The questions are answered in the article. The equivalence is not supposed to be obvious even to other number theorists. Most of the article is devoted to explaining "why" it works since the actual proof is two paragraphs.

[JoeAltmaier → hyperbovine]

Don't know what you're talking about. The article is about unproved theorems. They are described as being simple or obvious, but there's nothing obvious about

Prove that for n > 1, divsum(n) < H_n + exp(H_n)log(H_n)

why exp log? That's the question.

I believe that hyperbovine was referring to the article linked by tzs that explains the relation.
