Abstract
In this paper, we study the wave equation with sub-linearity in a ball with periodic-Dirichlet conditions. Combining the minimax principle with an approximation argument, we prove the existence of infinitely many time-periodic solutions for the problem. The proof also relies on the structure of the spectrum of the linearized problem.
