Who can help me calculating up to 10 exact decimal places sum (1/n^(1-1/n) - 1/n) sum (1/p^(1-1/p) - 1/p) sum (ln(n) / n^2) sum (ln(p) / p^2) n=positive...
An interesting extension of Patrick De Geest's Table is where 10^n+p and p are both prime (the first instance) The table begins: n---------p ============= ...

maybe... let Z = 2^(2^(p+1))+1 ; p is prime Z is prime iff [Z (mod (2^p+1))] == 2^q ; for some q for p = 2, 3,..., next??? eg. p=2, 2^8+1 mod 5 == 2^1 and... ...
Thanks for evaluations received. What I mean is: Can sum(ln(n)/n^2 ~ 0.93 reach 1? Can sum(ln(p)/p^2 ~ 0.49 reach 0.5? WDS ... [Non-text portions of this...

Hello, ... Consider the inequality sum(ln(k)/k^2, k=A+1..infinity) < integral(ln(k)/k^2, k=A..infinity) The right-hand side can be evaluated as (ln(A)+1)/A....
What is the probability of a number being square free... it seems that the more square free numbers than the non-square free numbers for big numbers. Would be...
... The density of numbers being nth-powerfree is 1/zeta(n), where zeta is the Riemann Zeta Function. So, for squarefree numbers, we have your probability is...

Using a similar trick, one can verify the sum over the primes is strictly less than 0.5. One overestimates the tail end of the sum: sum(log(t)/t^2,t=p to 00,...
