What Are the Key Properties of Non-Linear Water Waves?

Click For Summary
SUMMARY

The discussion centers on the mathematical properties of non-linear hydrodynamic waves, specifically focusing on radiation and modulational instability as described by the Korteweg-de Vries equation (fifth order). Key topics include spatial instabilities, chaos in high-order Hamiltonian algebra, and the characteristics of spatially quasi-periodic capillary-gravity waves. The participant emphasizes the importance of vorticity and Reynolds stress in turbulent flow and explores the application of stochastic calculus to model chaotic behavior in wave propagation. The conclusion highlights the use of the Inverse Scattering Transform on non-linear homogeneous partial differential equations to address these complexities.

I am currently studying non-linearity properties of hydrodynamic waves from a purely mathematical stance. At the moment, I am concerned with radiation, modulational instability described by korteweg-De Vries equation (fifth order) and Spatial Instabilities and chaos in a high order hamiltonian algebra. These characteristics of radiating wave tails that propagate outwards in what seems to be a chaotic manner are my concern. I am elaborating my analysis to focus primarily on the characteristics of Spatially quasi-periodic capillary-gravity waves using the Hamiltonian structures which describes the degeneracy of the water-wave problem.

With this in mind, my observations ideas consist of a 'turbulent flow' of incompressible fluids traveling through a differentiable manifold and experiencing a Reynold Stress on it's surface (vorticity is key),

How can I adapt a system of 'eddies' in flux with stochastic calculus (brownian motion). e.g: If I were to study a batch of wave propagation in a free surface, Is it possible for me to derive a system that can equally predict and forecast the random and chaotic behavior of it's sub-atomic particles? Dissipation at the Quantum Level comes to mind.

Thank you!

I think I wasn't explicit enough, but now I've succesfully solved my own troubles; I am treating this as an Inverse Scattering Transform on a non linear homogenous partial diff. with respect to frequency
