WebA solitary wave is a localized gravity wave that maintains its coherence and, hence, its visi-bility through properties of nonlinear hydrodynamics. Solitary waves have nite amplitude and propagate with constant speed and constant shape. Soliton Solitons are solitary waves that have an elastic scattering property: they retain their shape WebSoliton theory synonyms, Soliton theory pronunciation, Soliton theory translation, English dictionary definition of Soliton theory. n. A pulselike wave that can exist in nonlinear systems, does not obey the superposition principle, and does not disperse.

We found an envelope soliton solution of the third-order approximation equation of nonlinear wave dispersion theory (the so-called perturbed … 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. (Dispersive effects are a property of certain systems where the … See more A single, consensus definition of a soliton is difficult to find. Drazin & Johnson (1989, p. 15) ascribe three properties to solitons: 1. They are of permanent form; 2. They are localized within a region; See more In 1834, John Scott Russell describes his wave of translation.
