A note on the analytical solution to the modified perturbed Korteweg–de Vries equation

摘要

Motivated with a solitary wave type of solution to modified Korteweg–de Vries (KdV) equation, in this work we shall seek a travelling wave solution to the modified perturbed KdV equation. It is observed that the modified perturbed KdV equation still assumes a solitary wave solution with decaying amplitude in time.
