讲座简介：This talk will be discussing the distribution of the nontrivial zeros of the Dedekind Zeta function. Given the Dedekind Zeta function (s) (where is a number field, is any complex number), we consider the nontrivial zeros of function and then prove that all nontrivial zeros of have real part equal to , which states that the extended Riemann hypothesis is true. As a consequence, Riemann hypothesis is also true.
