WebThe prime number theorem describes the asymptotic distribution of prime numbers.

In a handwritten note on a reprint of his 1838 paper "Sur l'usage des séries infinies dans la théorie des nombres", which he mailed to Gauss, Dirichlet conjectured (under a slightly different form appealing to a series rather than an integral) that an even better approximation to π(x) is given by the offset logarithmic integral function Li(x), defined by Indeed, this integral is strongly suggestive of the notion that the "density" of primes around t sho… WebSep 1, 2024 · The function π (x) is known as the prime counting function. We call the related function p : R > 0 R defined by p ( x ) = π ( x ) x , x > 0 , the prime density function .
