Turing's method

In mathematics, Turing's method is used to verify that for any given Gram point gm there lie m + 1 zeros of ζ(s), in the region 0 < Im(s) < Im(gm), where ζ(s) is the Riemann zeta function.

[1] It was discovered by Alan Turing and published in 1953,[2] although that proof contained errors and a correction was published in 1970 by R. Sherman Lehman.

[3] For every integer i with i < n we find a list of Gram points

, where gi is the smallest number such that where Z(t) is the Hardy Z function.

Note that gi may be negative or zero.
