In this paper, the auxiliary equation method is successfully applied to compute analytical solutions for (3+1)-dimensional generalised Kadomtsev-Petviashvili and (2+1)-dimensional Gardner-Kadomtsev-Petviashvili equations, by introducing simple transformations. These results hold numerous travelling wave solutions that are of key importance which provide a powerful mathematical tool for solving nonlinear wave equations in recent era of applied science and engineering. The method can also be extended to other nonlinear evolution models arising in contemporary physics. [ABSTRACT FROM AUTHOR]

This paper investigates the analytical solutions of the perturbed nonlinear Schrödinger equation through the modified Khater method. This method is considered one of the most recent accurate analytical schemes in nonlinear evolution equations where it obtained many distinct forms of solutions of the considered model. The investigated model in this paper is an icon in quantum fields where it describes the wave function or state function of a quantum-mechanical system. The physical characterization of some obtained solutions in our study is explained through sketching them in two- and three-dimensional contour plots. The novelty of our study is clear by showing the matching between our solutions and those that have been constructed in previously published papers. [ABSTRACT FROM AUTHOR]

This study is about some new optical wave solutions to the time-fractional Kudryashov equation. The obtained solutions may be applied to demonstrate the nonlinear fractional model in a better way. These solutions are in the form of dark, singular, singular-dark solitons and other solutions with certain conditions. The obtained results were verified using Mathematica software. Modified integration method, the extended Jacobi’s elliptic expansion functions method, is utilised to secure the aforesaid solutions. These optical solitons suggest that this method is effective, straightforward and reliable compared to other methods. [ABSTRACT FROM AUTHOR]
