Solitary wave solutions, periodic and superposition solutions to the system of first-order (2+1)-dimensional Boussinesq's equations derived from the Euler equations for an ideal fluid model

Piotr Rozmej, Anna Karczewska

This article concludes the study of (2+1)-dimensional nonlinear wave equations that can be derived in a model of an ideal fluid with irrotational motion. In the considered case of…

(2+1)-dimensional KdV, fifth-order KdV, and Gardner equations derived from the ideal fluid model. Soliton, cnoidal and superposition solutions

Anna Karczewska, Piotr Rozmej

We study the problem of gravity surface waves for an ideal fluid model in the (2+1)-dimensional case. We apply a systematic procedure to derive the Boussinesq equations for a given…

Boussinesq's equations for (2+1)-dimensional gravity-surface waves in an ideal fluid model

Anna Karczewska, Piotr Rozmej

We study the problem of gravity surface waves for the ideal fluid model in (2+1)-dimensional case. We apply a systematic procedure for deriving the Boussinesq equations for a presc…

Inverted solutions of KdV-type and Gardner equations

Anna Karczewska, Piotr Rozmej

In most of the studies concerning nonlinear wave equations of Korteweg-de Vries type, the authors focus on waves of elevation. Such waves have general form ~$u_{\text{u}}(x,t)=A f(…

Signatures of chaotic dynamics in wave motion according to the extended KdV equation

Anna Karczewska, Piotr Rozmej

In this communication we test the hypothesis that for some initial conditions the time evolution of surface waves according to the extended KdV equation (KdV2) exhibits signatures…
