The zeta function values listed below include function values at the negative even numbers (s = −2, −4, etc.), for which ζ(s) = 0 and which make up the so-called trivial zeros. The Riemann zeta function article includes a colour plot illustrating how the function varies over a continuous rectangular region of the complex plane.
The Riemann zeta function ζ(z) plotted with domain coloring. [1] The pole at = and two zeros on the critical line.. The Riemann zeta function or Euler–Riemann zeta function, denoted by the Greek letter ζ (), is a mathematical function of a complex variable defined as () = = = + + + for >, and its analytic continuation elsewhere.
These are called its trivial zeros. The zeta function is also zero for other values of s, which are called nontrivial zeros. The Riemann hypothesis is concerned with the locations of these nontrivial zeros, and states that: The real part of every nontrivial zero of the Riemann zeta function is 1 / 2 .
Z function in the complex plane, plotted with a variant of domain coloring. Z function in the complex plane, zoomed out. In mathematics, the Z function is a function used for studying the Riemann zeta function along the critical line where the argument is one-half.
English: This is a polar plot of the first 20 non-trivial Riemann zeta function zeros (including Gram points along the critical line (/ +) for real values of running from 0 to 50. The consecutive zeros have 50 red plot points between each with zeros identified by magenta concentric rings (scaled to show the relative distance between their ...
This image shows the path of the Riemann zeta function along the critical line. That is, it is a graph of ℜ ζ ( i t + 1 / 2 ) {\displaystyle \Re \zeta (it+1/2)} versus ℑ ζ ( i t + 1 / 2 ) {\displaystyle \Im \zeta (it+1/2)} for real values of t running from 0 to 34.
These conjectures – on the distance between real zeros of (+) and on the density of zeros of (+) on intervals (, +] for sufficiently great >, = + and with as less as possible value of >, where > is an arbitrarily small number – open two new directions in the investigation of the Riemann zeta function.
In mathematics, the Riemann–von Mangoldt formula, named for Bernhard Riemann and Hans Carl Friedrich von Mangoldt, describes the distribution of the zeros of the Riemann zeta function. The formula states that the number N(T) of zeros of the zeta function with imaginary part greater than 0 and less than or equal to T satisfies
