| Nov 1, 2012 at 3:51 | comment | added | fedja | Sorry for an idiotic question: I misread "concave" as "convex". In what sense is the growth you want "the fastest"? It is not hard to show that you cannot beat $1/(4x^2)$ everywhere on any interval $(0,a)$ but you can go a bit above it at places at the cost of going below it at some other places... | |
