Abstract In this paper, a (2+ 1)-dimensional generalized Konopelchenko-Dubrovsky-Kaup- Kupershmidt system in fluid mechanics and plasma physics is investigated. Bilinear form …
This paper proposes a new integrable generalized (3+ 1)-dimensional nonlinear partial differential equation. We apply the standard Painlevé test to check the integrability, which …

This work investigates a (2+ 1)-dimensional shallow water wave equation of ion-acoustic waves in plasma physics. It comprehensively analyzes Cole–Hopf transformations …
By imposing a nonlocal reverse-time type constraint on a general coupled nonlinear Schrödinger (NLS) equation, we propose a novel nonlocal reverse-time NLS equation which …
By imposing a nonlocal reverse-space symmetry constraint on a general coupled nonlinear Schrödinger (NLS) equation, we propose a new general nonlocal reverse-space NLS …
In this work, we have derived a new (2+ 1)-dimensional Schrödinger equation that contains separated real and imaginary parts of the dependent variable as follows iw tx+ iwt-w xx+ w …

In this paper, we analyzed the (3+ 1)-dimensional Benjamin–Ono (BO) equation. We first demonstrated that the governing model is not integrable in the Painlevé sense. The rogue …
This paper aims to study versatile excitations of (3+ 1)-dimensional partially nonlocal bright– bright Peregrine-quartets in a nonautonomous vector nonlinear Schrödinger equation with …
