Abstract
In this paper, we construct the quasi-periodic wave solutions of the associated Camassa–Holm equation based on the bilinear Bäcklund transformation and Riemann theta function. We demonstrate that the dynamic characteristics of the one- and two-periodic waves under different parameter conditions. The relations between the periodic wave solutions and the corresponding soliton solutions are established through the asymptotic properties.
期刊介绍:
The purpose of Applied Mathematics Letters is to provide a means of rapid publication for important but brief applied mathematical papers. The brief descriptions of any work involving a novel application or utilization of mathematics, or a development in the methodology of applied mathematics is a potential contribution for this journal. This journal''s focus is on applied mathematics topics based on differential equations and linear algebra. Priority will be given to submissions that are likely to appeal to a wide audience.
