<p>Here  are the zeros of the Riemann zeta function in the critical strip, where the real part of  is between zero and one. The formula is valid for values of  greater than one, which is the region of interest. The sum over the roots is <a href="page.php?w=Conditional_convergence">conditionally convergent</a>, and should be taken in order of increasing <a href="page.php?w=absolute_value">absolute value</a></p><p>
