内容先容:In this talk, we discuss the Camassa-Holm equation, which is a model for shallow  water waves. We first establish the existence of solitary wave solutions for the  equation without delay. And then we prove the existence of solitary wave  solutions for the equation with a special local delay convolution kernel and a  special nonlocal delay convolution kernel by using the method of dynamical  system, especially the geometric singular perturbation theory and invariant  manifold theory. According to the relationship between solitary wave and  homoclinic orbit, the Camassa-Holm equation is transformed into the ordinary  differential equations with fast variables by using the variable substitution.
