New travelling wave solutions of two nonlinear physical models by using a modified tanh-coth method

摘要

In this work, a modified tanh - coth method is used to derive travelling wave solutions for (2 + 1)-dimensional Zakharov-Kuznetsov (ZK) equation and (3 + 1)-dimensional Burgers equation. A new variable is used to solve these equations and established new travelling wave solutions.
