Abstract:
本文研究具有时空卷积的Wazwaz-Benjamin-Bona-Mahony (WBBM)方程孤立波和周期波的存在性。根据几何奇异摄动理论，将一个非线性偏微分方程转化为平面二维动力系统。基于Melnikov方法，可以判断出扰动WBBM方程的孤立波和周期波是不存在的。
This paper discusses the existence of solitary waves and periodic waves for Wazwaz-Benjamin-Bona-Mahony (WBBM) equation with spatiotemporal convolution. According to the theory of geometric singular perturbations, a nonlinear partial differential equation is transformed into a two-dimensional planar dynamical system. Based on the Melnikov method, it can be determined that solitary waves and periodic waves of perturbed WBBM equation do not exist.
