====== The Riemann hypothesis ====== - was proposed by //Bernhard Riemann// (1859), and is a conjecture about the distribution of the zeros of the //Riemann zeta function//. The Riemann hypothesis asserts that all interesting solutions of the equation : $$ {\displaystyle \zeta (s)=\sum _{n=1}^{\infty }{\frac {1}{n^{s}}},} $$ lie on a certain vertical straight line. Expressed as : “Every nontrivial zero of the Riemann zeta function has real part 1/2.” It remains unproved whether the hypothesis is true or false.
