New sets of soliton solutions for the generalized Whitham–Broer–Kaup–Boussinesq–Kupershmidt system

Abstract

Nonlinear evolution equations play a crucial role in modelling various physical phenomena, such as fluid flow dynamics and plasma waves. Among them, the generalized Whitham–Broer–Kaup–Boussinesq–Kupershmidt (WBKBK) system, along with its special cases, has garnered significant attention in the study of soliton theory due to its intricate mathematical structure and broad range of applications. This study explores the properties and behaviour of soliton solutions in the WBKBK system. The study presents six new classes of wavelike solutions of the WBKBK system and investigate the unique characteristics exhibited by dark and anti-dark solitons, as well as the phenomenon of forward and backward propagating solitons in the system. These findings contribute to a deeper understanding of the fundamental dynamics of the WBKBK system and offer valuable insights into soliton solutions of the system.
