Abstract ：
This paper is concerned with the Cauchy problem for a weakly dissipative 3-component Camassa-Holm system. We first obtain the local well-posedness of solutions by using Kato's theory. We then derive the wave breaking mechanism of solutions, and give two wave breaking criteria for solutions by the method of characteristic and convolution estimates. Finally, we prove that if the initial data with their derivatives of the system exponentially decay at infinity, then the corresponding solution also exponentially decays at infinity.

Abstract ：
In this paper, we investigate the existence of multiple nontrivial periodic solutions for an asymptotically linear wave equation with x-dependent coefficients. Such a mathematical model can be derived from the forced vibrations of a nonhomogeneous string and propagation of seismic waves in nonisotropic media. By constructing a suitable function space, we characterize the problem as a variational problem, and then we prove that there are at least three nontrivial periodic solutions via variational methods.

Abstract ：
In this paper, we consider the one-dimensional Kirchhoff equation with x-dependent coefficients under the spatial periodic conditions, which models the forced vibrations of an inhomogeneous string in presence of a time periodic external forcing with period 2 pi/omega and amplitude E>0. By using the Lyapunov-Schmidt reduction and the Nash-Moser iteration technique, we obtain the existence, regularity and local uniqueness of time periodic solutions with period 2 pi/omega and order E. Such results hold for parameters (omega ,E) in a positive measure Cantor set that has asymptotically full measure as the amplitude E goes to zero.
