24303Re: Prime sieving on the polynomial f(n)=n^2+1
- Jul 5 12:29 PMHello Bernhard,
Looking at table 4a, it seems to present column c as the number of primes up to 2^n, and column d as the number of primes of the form x^2+1 up to 2^n. But the numbers can't be correct so am I misunderstanding something?
I'm looking at the small table 5b where it seems you extrapolate the number of primes of the form x^2+1 which are between 2^n and 2^(n+1). The number of such primes is decreasing as n increases, but it seems to me it should be going up.
You wrote in the conclusion,
"The density of the distribution of the primes p=x^2+1 goes surely to zero.
Supposing that the exploration of the second scenario is rigth, it could be supposed that the primes of the form x^2+1 are limited."
Are you saying that the number of primes of the form x^2+1 appears to be finite?
