New exact travelling wave solutions of generalised sinh- Gordon and (2 + 1)-dimensional ZK-BBM equations

Exact travelling wave solutions have been established for generalised sinh-Gordon andgeneralised (2+1) dimensional ZK-BBM equations by using GG expansion method whereG G( ) satisfies a second-order linear ordinary differential equation. The travelling wave solutionsare expressed by hyperbolic, trigonometric and rational functions.
