An Estimate of a Special Exponential Sum

Mathematische Nachrichten, 1986
The exponential sums \(\sum^{n}_{k=1}k^{2\pi ir}\), \(\sum^{\infty}_{k=1}k^{2\pi ir} e^{-k^ 2/n}\), and \(\sum^{n}_{k=1}k^{2\pi ir-1}\) are considered. These are closely related to Riemann's zeta-function (though the zeta-function is not mentioned in the paper), and the main results of the paper are either well-known from the theory of the zeta ...
