In this study, we have applied the modified exp -expansion function method (MEFM) to obtain exact travelling wave solutions for (3+1) dimensional Khokhlov–Zabolotskaya–Kuznetsov (KZK) equation and (3+1)-dimensional Jimbo-Miwa (JM) equation. Dark soliton solution, dark-bright hyperbolic solution trigonometric of KZK JM been found by using method. After that, scratched 2D 3D graphs all obtained i...

A new extended (G′/G)-expansion method is presented in this paper to construct more general type and new traveling wave solutions of nonlinear partial differential equations. To illustrate the novelty and advantage of the proposed method, we solve the (3+1)-dimensional Jimbo-Miwa equation. Abundant exact traveling wave solutions of this equation is obtained, which successfully recover most of t...

We have worked on (2+1)-dimensional dissipative long wave system (DLWS) and Date-Jimbo-Kashiwara-Miwa (DJKM) equation. applied GKM, which has been obtained by generalizing the Kudryashov method, to (2+1)- dimensional DLWS DJKM Thus, we got some new soliton solutions of handled plotted 2D 3D surfaces these acquired results using Wolfram Mathematica 12. Then, shown validity solutions.
