# Riemann hypothesis

- kind: problem
- status: open
- year: 1859
- authors: Bernhard Riemann

**Statement.** Every nontrivial zero of the Riemann zeta function has real part 1/2.

The zeta function encodes the primes, and the location of its zeros controls how far the count of primes up to x can stray from its smooth estimate. If the hypothesis holds, the error is about the square root of x, the best that could be hoped for. Over ten trillion zeros have been computed and all lie on the line. Hundreds of theorems are proved conditionally on it, so a proof would settle them all at once. The analogue for curves over finite fields was proved by Deligne in 1974, which is the strongest evidence that the statement is true and the main source of ideas for attacking it.

Posed 1859, Bernhard Riemann.
