Joint Universality for the Riemann zeta-function with general shifts

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 shifts by Andersson et al. In this paper, we generalize their result for the joint universality theorem for the Riemann zeta-function with general shifts using a different approach from their method.
