Linear Partial Differential Equations, problems in applied mathematics, mathematical physics, and engineering science. This subject plays a central role in modern mathematical sciences, especially in physics, geometry and analysis. Many problems of physical interest are described by partial differential equations with appropriate initia

,Nonlinear Dispersive Waves and Whitham’s Equations,ence of periodic wavetrains that are possible in nonlinear dispersive wave systems. He also determined that the dispersion relation involves the wave amplitude. The dependence of the dispersion relation on the amplitude produces significant qualitative changes in the behavior of nonlinear waves. It

Solitons and the Inverse Scattering Transform,r lead to breaking phenomena of the typical hyperbolic kind with the development of a vertical profile. In particular, the dispersive term in the Korteweg-de Vries equation does prevent this from ever happening in its solution. In general, breaking can be prevented by including dispersive effects in
