Relations among the Riemann zeta and Hurwitz zeta functions as well as their products

Abstract

Several relations are obtained among the Riemann zeta and Hurwitz zeta functions, as well as their products. A particular case of these relations give rise to a simple re-derivation if the important results of [11]. Also, a relation derived here provides the starting point of a novel approach which in a series of companion papers yields a formal proof of the Lindelöf hypothesis. Some of the above relations motivate the need for analysing the large $\alpha$ behaviour of the modified Hurwitz zeta function ${\zeta }_1(s,\alpha )$, $s\in \mathbf{C}$, $\alpha \in \mathbf{R}$, which is also presented here.
