报告摘要： This talk is concerned with the periodic solutions of nonlinear wave equation with x-dependent coefficients, which arises from the forced vibrations of an inhomogeneous string and the propagation of seismic waves in nonisotropic media. We shall talk about some recent results on the existence of periodic solutions for such a model, especially the two-dimensional case.
