Rossby Solitary Waves Generated by Wavy Bottom in Stratified Fluids
Advances in Mechanical Engineering, 2013 Rossby solitary waves generated by a wavy bottom are studied in stratified fluids. From the quasigeostrophic vorticity equation including a wavy bottom and dissipation, by employing perturbation expansions and stretching transforms of time and space, a ...

Large amplitude dust-acoustic solitary waves and double layers in nonthermal warm complex plasmas
AIP Advances, 2023 Using a Sagdeev pseudo-potential approach, where the nonlinear structures are stationary in a comoving frame, the arbitrary or large amplitude dust-acoustic solitary waves and double layers have been studied in dusty plasmas containing warm positively ...

Nonexistence of Subcritical Solitary Waves [PDF]
Archive for Rational Mechanics and Analysis, 2021 AbstractWe prove the nonexistence of two-dimensional solitary gravity water waves with subcritical wave speeds and an arbitrary distribution of vorticity. This is a longstanding open problem, and even in the irrotational case there are only partial results relying on sign conditions or smallness assumptions.

Solitary waves and Bohmian mechanics [PDF]
Proceedings of the National Academy of Sciences, 2002 We study a Schrödinger-like equation with a nonlinear term. This nonlinearity has the effect of allowing the existence of highly concentrated stable solitary waves of a topological nature. Such solitary waves tend to move according to Bohmian mechanics. Therefore our model can be considered a nonsingular realization of de Broglie pilot wave theory.

Boson Stars as Solitary Waves [PDF]
Communications in Mathematical Physics, 2007 We study the nonlinear equation equation presented which is known to describe the dynamics of pseudo-relativistic boson stars in the mean-field limit. For positive mass parameters, m > 0, we prove existence of travelling solitary waves, equation presented , for some equation presented and with speed |v| < 1, where c = 1 corresponds to the speed ...
