On a mollifier of the perturbed Riemann zeta-function

Abstract

The mollification $ζ(s) + ζ'(s)$ put forward by Feng is computed by analytic methods coming from the techniques of the ratios conjectures of $L$-functions. The current situation regarding the percentage of non-trivial zeros of the Riemann zeta-function on the critical line is then clarified.
