I know from papers like Dusarts's that $$nleft(ln n +ln ln n -1+ fracln ln n -2ln n-fracln^2 ln n -6 ln ln n +122 ln^2 nright) leq p_n leq nleft(ln n +ln ln n -1+ fracln ln n -2ln n-fracln^2 ln n -6 ln ln n +102 ln^2 nright) $$



But could any one give and explicit number $n_0$ for which for all $n geq n_0$ the above inequalities hold true ?



It does not have to be the smallest one, also if there is way, could you please show me how to get this number



I read a paper that estimate that the $n_0 approx 3.9*10^31$ under the R.H.
if we don't assume R.H. could we still have $n_0 ll 10^100$



Thanks in advance

This question has not received enough attention.


Give a ref to a paper dealing with this problem, or give a proof about the $n_0$ number, Thanks















  • These bounds are much tighter than the one mentioned in Wikipedia! Did the paper mentioned a proven bound (not assuming RH) ?
