报告摘要:
In this talk, we discuss perturbed Camassa-Holm and Camassa-Holm-KP equations, which are models for shallow water waves. We establish the existence of solitary wave solutions for these equations without delay. And then we prove the existence of solitary wave solutions for the equations with local and nonlocal delay convolution kernels by using the method of dynamical system, especially the geometric singular perturbation theory and invariant manifold theory. We prove that these equations with disturbance also possesses homoclinic orbit, and there exists solitary wave solution of the delayed Camassa Holm and Camassa-Holm-KP equationse.
