We consider solutions of hyperbolic conservation laws regularized with vanishing diffusion and dispersion terms. Following a pioneering work by Schonbek, we establish the convergence of the regularized solutions toward discontinuous solutions of the hyperbolic conservation law. The proof relies on the method of compensated compactness in the L2 by: Figure 8: Dispersion relation for deep water gravity waves. Dashed lines show the shallow water relation. the departure from shallow water behavior4 for kD > 1. In general, the most important di⁄erence is that, for deep water waves, the phase speed c =!=k is not independent of wavenumberŠ such waves are known as dispersive waves. File Size: KB.

velocity of dispersive waves di⁄ers from the phase speed, so in a wave packet like that shown in Fig. 7 the wave crests will move at a di⁄erent speed than the envelope. If c > c g (which, as we shall see, is the case for deep water waves), new wave crests appear at the rear of the wave packet, move forwardFile Size: KB.

Cited by: Dispersionless (or quasi-classical) limits of integrable partial differential equations (PDE) arise in various problems of mathematics and physics and have been intensively studied in recent literature (see e.g.

A kinetic decomposition for singular limits of non-local conservation laws methods is not available but we will present several results on singular limits [5].

Nonlinear dispersive waves. In mathematics and physics, the Kadomtsev–Petviashvili equation – or KP equation, named after Boris Borisovich Kadomtsev and Vladimir Iosifovich Petviashvili – is a partial differential equation to describe nonlinear wave KP equation is usually written as: ∂ (∂ + ∂ + ∂) + ∂ = where = ±.The above form shows that the KP equation is a generalization to two spatial.

Despite the singular nature of the zero-diffusion limit and rather differing analytical approaches employed in the descriptions of dispersive and diffusive-dispersive regularization, the Cited by: Waves in a Dispersive Medium Dispersion causes the shape of a wave pulse to change as it travels If the wave speed depends only on the physical properties of the medium (i.e., the elastic and inertia properties of a mechanical medium, or the relative permeability and permittivity for EM waves) then the wave speed is a constant, independent of.

The field of nonlinear dispersive waves has developed enormously since the work of Stokes, Boussinesq and Korteweg-de Vries (KdV) in the nineteenth century.
