Topic:Periodic solutions of nonlinear wave equation with x-dependent coefficients

Reporter:Ji Shuguan

Time: December 1(Tuesday)10: 30-11: 20a.m.

Site:Tencent meeting Meeting ID:538 611 138

Abstract:This talk is concerned with the periodic solutions of nonlinear wave equation with x-dependent coefficients. Such a model arises from the forced vibrations of an inhomogeneous string and the propagation of seismic waves in inhomogeneous media. We shall give some existence results on the periodic solutions of such a model with different types of nonlinearity.
