In this paper, some novel analytical approximations to a completely non-integrable
nonplanar (cylindrical and spherical) Kawahara equation (nKE) are derived. Using the …

Multi-soliton interaction of nonlinear ion sound waves in a pair-ion–electron (PIE) plasma
having non-Maxwellian electrons including Kappa, Cairns, and generalized two spectral …

Ion-acoustic waves are investigated in an unmagnetized collisionless plasma comprising
dynamical ions and inertialess cold and hot (C–H) electrons expressed by Maxwellian …

The presence of the geometrical curvature makes the planar Korteweg–de Vries (KdV)
equation inadequate to describe the propagation of nonlinear waves. In many scientific …

In this paper, the modulational instability (MI) of the high-frequency electron-acoustic waves
(EAWs) is reported in a non-Maxwellian plasma composed of two distinct types of electrons …

This study aims to examine the properties of the nonplanar (cylindrical and spherical) ion-
acoustic solitary waves (SWs) and cnoidal waves (CWs) in a collisionless, unmagnetized …

This study investigates the wave solutions of the time-fractional Sawada–Kotera–Ito
equation (SKIE) that arise in shallow water and many other fluid mediums by utilizing some …

Abstract The (2+ 1)-dimensional combined Zakharsov-Kuznetsov-modified Zakarsov-
Kuznetsov (ZK-mZK) equation with constant co-efficients are solved by employing the …

In this work, a novel technique is considered for analyzing the fractional-order Jaulent-
Miodek system. The suggested approach is based on the use of the residual power series …

This study is made to extract the exact solutions of Korteweg–de Vries–Burgers (KdVB)
equation and Korteweg–de Vries (KdV) equation. The original idea of this work is to …
