摘要

Traveling wave solutions have been well studied for various nonlinear systems.However,for high order nonlinear physical models,there still exist various open problems.Here,travelling wave solutions to the well-known fifthorder nonlinear physical model,the Sawada-Kotera equation,are revisited.Abundant travelling wave structures including soliton molecules,soliton lattice,kink-antikink molecules,peak-plateau soliton molecules,few-cyclepulse solitons,double-peaked and triple-peaked solitons are unearthed.
