# Zeros of Dirichlet polynomials

Turan showed that if for all sufficiently large , the th partial sum of does not vanish in then the Riemann Hypothesis follows.

He [ MR 10,286a] strengthened this criterion by showing that for every there is an such that if the th partial sum

of the zeta-function has no zeros in for all then the Riemann Hypothesis holds.

H. Montgomery [ MR 87a:11081] proved that this approach cannot work because for any positive number the th partial sum of has zeros in the half-plane
