Soliton molecules can be formed in both theoretical and experimental situations. In this paper, a new velocity resonance is introduced, which can form soliton molecules for the (2 + 1)-dimensional Sawada–Kotera equation. By selecting some suitable parameters for soliton molecules, the asymmetric solitons of the (2 + 1)-dimensional Sawada–Kotera equation can be obtained. In mathematics and physics, a soliton or solitary wave is a self-reinforcing wave packet that maintains its shape while it propagates at a constant velocity. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. (The term "dispersive effects" refers to a property of certain systems where the speed of the waves varies according to frequency.) · A nonlinear wave equation permitting topological vortices is proposed, which is a two-spatial-dimensional analogue of the classical continuous isotropic Heisenberg spin chain. Exact multi-vortex solutions of the equation are obtained by using Hirota's method. This shows that the dynamics of vortices are integrable. The method to derive dark solitons can also be extended to other nonlinear wave equations, which are useful to study the dynamics of nonlinear localized waves analytically. The results in this paper further reveal the intriguing dynamic distributions of localized waves in the CNLS equations with four-wave mixing, and we hope our results can be verified in real experiments in the future. An Introduction to Solitons. Alex Kasman / College of Charleston. we can actually solve some nonlinear equations exactly, ... Here's a movie (where each frame of the movie comes from a different value of t) showing what this 2-soliton solution looks like as the two humps meet. We performed numerical simulation of an ensemble of nonlinearly interacting free gravity waves (swell) by two different methods: solution of primordial dynamical equations describing potential flow of the ideal fluid with a free surface and, solution of the kinetic Hasselmann equation, describing the wave ensemble in the framework of the theory Nonlinear waves are described by nonlinear equations, and therefore the superposition principle does not generally apply. This means that nonlinear wave equations are more difficult to analyze mathematically and that no general analytical method for their solution exists. Solitons and Nonlinear Wave Equations.
