Lie Symmetry Analysis of Kudryashov‐Sinelshchikov Equation [PDF]
The Lie symmetry method is performed for the fifth‐order nonlinear evolution Kudryashov‐Sinelshchikov equation. We will find ones and two‐dimensional optimal systems of Lie subalgebras. Furthermore, preliminary classification of its group‐invariant solutions is investigated.

On the Solutions for a Fifth Order Kudryashov–Sinelshchikov Type Equation
The fifth order Kudryashov–Sinelshchikov equation models the evolution of the nonlinear waves in a gas–liquid mixture, taking into account an interphase heat transfer, surface tension, and weak liquid compressibility simultaneously at the derivation of the equations for non-linear-waves.

A singular limit problem for the Kudryashov-Sinelshchikov equation [PDF]
We consider the Kudryashov-Sinelshchikov equation, which contains nonlinear dispersive effects. We prove that as the diffusion parameter tends to zero, the solutions of the dispersive equation coverge to the entropy ones of the Burgers equation. The proof relies on deriving suitable a priori estimates together with an application of the compansated ...

Exact solutions of the generalized nonlinear Fokas-Lennells equation
Two different schemes are applied to the generalized nonlinear Fokas-Lennells equation for obtaining possible optical solitonic solutions at general orders of nonlinearities. It is known that the standard Kudryashov method leads to singular combo optical

Optical solitons with Kudryashov’s sextic power-law nonlinearity
Objective - The main objective of this paper is to investigate analytic soliton solutions of a nonlinear Schrodinger equation (NLSE), including Kudryashov's sextic power-law nonlinearity by introducing different approaches of two efficient analytical methods. The considered equa-tion has been recently introduced by N. A.

New wave behaviors of the Fokas-Lenells model using three integration techniques.
In this investigation, we apply the improved Kudryashov, the novel Kudryashov, and the unified methods to demonstrate new wave behaviors of the Fokas-Lenells nonlinear waveform arising in birefringent fibers.
