In this work, we study the dynamic properties of the transformed nonlinear waves of the six-order nonlinear Schrödinger equation. The breather wave of the equation is obtained based on the Darboux transformation. In order to study the state transition, we give the transition conditions of the breather wave. Based on this transition condition, the breather wave is transformed into various types of nonlinear waves, including W-shaped solitons, M-shaped solitons, multi-peak solitons, oscillation solitons, etc. Furthermore, the oscillation properties of these transformed nonlinear waves are analyzed. Finally, these transformed nonlinear waves are graphically presented. [ABSTRACT FROM AUTHOR]

Abstract We consider the Heisenberg ferromagnetic spin chain equation, which is governed by the (2+1)-dimensional nonlinear Schrödinger-type equation. Based on the Ablowitz–Kaup–Newell–Segur frame, we study the integrability of the equation by deriving its Lax pair and infinite conservation laws. By introducing a potential transformation, we obtain its Hirota bilinear form and soliton solutions. Based on the resulting lax pair, we construct Darboux transformation and multi-soliton solutions of the equation. Furthermore, we also find the other type of soliton solutions for the equation by considering its Bäcklund transformation. Finally, we discuss the linear stability analysis by considering its stability condition for the stationary solution of the equation, which can be used to analyze modulation instability. The technique presented in this work is analytical, which can be used to enrich the dynamical of the Heisenberg ferromagnetic spin chain equation. [ABSTRACT FROM AUTHOR]

Abstract We consider the (3+1)-dimensional Boiti–Leon–Manna–Pempinelli equation, which can be used to describe the incompressible fluid. We derive the Hirota bilinear form of the equation via the Bell polynomial. By using Hirota's direct method, we obtain the N -soliton wave solutions of the equation. Based on the resulting Hirota's bilinear equation, we directly derive the breather wave solutions and rational solutions of the equation. Moreover, we employ the long wave limit method to derive the first-order and second-order rational solutions. In order to better understand the dynamical behaviors of the equation, we provide some graphical analyses to discuss the properties for the dynamic behaviors of these solutions.

In this work, we investigate the (3+1)-dimensional generalized B-type Kadomtsev–Petviashvili (gBKP) equation in fluid dynamics, which plays an important role in depicting weakly dispersive waves propagated in a quasi-media and fluid mechanics. By employing Hirota's bilinear method, we derive the one- and two-soliton solutions of the equation. Moreover, we reduce those soliton solutions to the periodic line waves and exact breather waves by considering different parameters. A long wave limit is used to derive the rogue wave solutions. Based on the resulting bilinear representation, we introduce two types of special polynomial functions, which are employed to find the lump solutions and interaction solutions between lump and stripe soliton. It is hoped that our results can be used to enrich dynamic behaviours of the (3+1)-dimensional BKP-type equations. [ABSTRACT FROM AUTHOR]

Under investigation in this paper is the (4+1)-dimensional nonlinear Fokas equation, which is an important physics model. With the aid of Bell’s polynomials, an effective and straightforward method is presented to succinctly construct the bilinear representation of the equation. By using the resulting bilinear formalism, the soliton solutions and Riemann theta function periodic wave solutions of the equation are well constructed. Furthermore, the extended homoclinic test method is employed to construct the breather wave solutions and rogue wave solutions of the equation. Finally, a connection between periodic wave solutions and soliton solutions is systematically established. The results show that the periodic waves tend to solitary waves under a limiting procedure.

In this paper, the extended nonlinear Schrödinger equation with higher-order odd (third order) and even (fourth order) terms is investigated, whose particular cases are the Hirota equation, the Sasa-Satsuma equation and Lakshmanan-Porsezian-Daniel equation by selecting some specific values on the parameters of higher-order terms. We first study the stability analysis of the equation. Then, using the ansatz method, we derive its bright, dark solitons and some constraint conditions which can guarantee the existence of solitons. Moreover, the Ricatti equation extension method is employed to derive some exact singular solutions. The outstanding characteristics of these solitons are analyzed via several diverting graphics.
