(G′/G, 1/G)-Expansion method for generalized ZK, Sharma–Tasso–Olver (STO) and modified ZK equations

The ( G ′/ G , 1/ G )-expansion method is one of the most direct and effective methods for obtaining exact traveling wave solutions of nonlinear partial differential equations (PDEs). In this paper, we construct exact travelling wave solutions of nonlinear evolution equations in mathematical physics via generalized Zakharov-Kuznetsov (ZK), modified Zakharov-Kuznetsov and Sharma–Tasso–Olver (STO) equations by ( G ′/ G , 1/ G )-expansion method, where satisfies the auxiliary ordinary differential equation (ODE) ; λ and μ are arbitrary constants.
