摘要：
In this paper, we consider a class of wave equations with linear couplings. Such model arises when two waves propagate simultaneously. Based on variational methods and Galerkin approximation argument, we obtain some multiplicity results of periodic solutions for the problem when the linear coupling coefficient epsilon is small enough and the nonlinearities satisfy superlinear growth.
