Abstract

We study the problem on how to get good lower estimates for the integral TT+Hζ(σ+it)dt, \int_T^{T+H} |\zeta(\sigma+it)| dt, when H1H \ll 1 is small and σ\sigma is close to 11, as well as related integrals for other Dirichlet series, by using ideas related to the Balasubramanian-Ramachandra method. We use kernel-functions constructed by the Paley-Wiener theorem as well as the kernel function of Ramachandra. We also notice that the Fourier transform of Ramachandra's Kernel-function is in fact a KK-Bessel function. This simplifies some aspects of Balasubramanian-Ramachandra method since it allows use of the theory of Bessel-functions.
