Effective hybrid joint universality for Dirichlet -functions and its application
Keita Nakai
In 2003, Garunkštis provided a lower bound for the lower density of the universality theorem for the Riemann zeta-function. In this paper, we generalize this result for the hybrid…
Notes on Universality in Short Intervals and Exponential Shifts
Johan Andersson, Ramūnas Garunkštis, Roma Kačinskaitė +6
We improve a recent universality theorem for the Riemann zeta-function in short intervals due to Antanas Laurinčikas with respect to the length of these intervals. Moreover, we pro…
Joint Universality for the Riemann zeta-function with general shifts
Keita Nakai
Laurinčikas proposed that whether the universality theorem for the Riemann zeta-function shifted by an exponential function holds or not. This problem is solved for more general sh…
Discrete universality for Matsumoto zeta-functions and the nontrivial zeros of the Riemann zeta-function
Keita Nakai
In 2017, Garunkštis, Laurinčikas and Macaitienė proved the discrete universality theorem for the Riemann zeta-function sifted by the nontrivial zeros of the Riemann zeta-function.…
