description
In 1859 B. Riemann published his groundbreaking work `` On the number of prime numbers under a given size ''. The thesis deals with the zeta function and its connection with the function pi (x), which gives the number of prime numbers less than or equal to x. The zeta function is initially defined as the infinite sum of 1 / n ^ s over all natural numbers n. The series converges for real s greater than 1. Riemann also considers the function for complex s and shows that it is analytically integrated into the whole complex plane can be continued with a single pole of the first order at the point s = 1. In addition, Riemann proves a functional equation for the zeta function and suggests that all non-real zeros of zeta (s) have the real part 1/2. Although this was confirmed numerically for more than a billion zeros, the Riemann Hypothesis (which is also one of the Millennium Problems) is still unproven to this day. In this lecture (on the 150th anniversary of the Riemann Hypothesis) we introduce the zeta function, use it to prove the prime number theorem that pi (x) is asymptotically equal to x / log (x) and discuss some implications and equivalences to the Riemann Hypothesis.
