Many consider it to be the most important unsolved problem in pure mathematics. It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.     egin{alertblock}{Riemann Hypothesis}         Riemann $zeta$ function         [             zeta(s)= - frac{Gamma(1-s)}{2pi i} int_{C} frac{(-z)^{s-1}}{e^z-1} {
