报告摘要:In this paper we investigate the uniqueness of periodic wave solutions for a 4-parametric perturbed KP-MEW equation with local strong delay convolution kernel. Applying the geometric singular perturbation theory, a locally invariant manifold is established in a small neighborhood of the critical manifold to transform the singular perturbed system into a regular one. We prove the monotonicity of the ratio of two Abelian integrals and give all conditions for the uniqueness of periodic wave solutions. Moreover, we find that the amplitude and wavelength of this periodic wave change monotonously following monotonous variation of some parameters included in the perturbed KP-MEW equation as shown as in numerical simulations.
