报告摘要By using geometric singular perturbation theory, Abel integral and Melnikov method, solitary waves and periodic solutions in the shallow water wave equations are showed to exist under nonlocal perturbations. It is found that solitary waves will persist with the nonlocal perturbation, there are some cases completely different from the local situation. Other interesting results, such asymptotic speed of waves, are also found. KdV and ZK-KS equations are taken as the examples.
