For \(\operatorname{Re} s>1\) let \(G(s)\) be the function defined by \(G(s)=\sum_{\gamma>0}\gamma^{-s}\), where \(\gamma\) denotes the ordinates of complex zeros of the Riemann zeta-function \(\zeta(s)\), and for \(0<\operatorname{Re} s\leq 1\) by analytic continuation. The main result is: For \(\sigma\) fixed we have \[ \int_1^T|G(\sigma+it)|^2 dt\ll\begin{cases} T,&1/2<\sigma\leq 1 \\T\log^2T, &\sigma=1/2\\T^{2-2\sigma}\log T,&0<\sigma<1/2.\end{cases} \] Certain integrals involving the function \(S(T)\), that is closely related to \(G(s)\), are also considered.
