# The numerical evaluation of the Riesz function

@inproceedings{Paris2021TheNE, title={The numerical evaluation of the Riesz function}, author={Richard B. Paris}, year={2021} }

The behaviour of the generalised Riesz function defined by Sm,p(x) = ∞ ∑ k=0 (−)x k!ζ(mk + p) (m ≥ 1, p ≥ 1) is considered for large positive values of x. A numerical scheme is given to compute this function which enables the visualisation of its asymptotic form. The two cases m = 2, p = 1 and m = p = 2 (introduced respectively by Hardy and Littlewood in 1918 and Riesz in 1915) are examined in detail. It is found on numerical evidence that these functions appear to exhibit the x and x decay… Expand

It is proved that the Riemann hypothesis is equivalent to c k ≪ k − 3 / 4 + e for all e > 0 and that c k implies that the zeros of ζ ( s ) are simple. Expand
