Existence of Multiple Periodic Solutions for a Semilinear Wave Equation in an n-Dimensional Ball
This paper is devoted to the study of periodic solutions for a radially symmetric semilinear wave equation in an n-dimensional ball. By combining the variational methods and saddle point reduction technique, we obtain the existence of at least three periodic solutions for arbitrary space dimension n...
