Self-Similar Solutions of the Non-Strictly Hyperbolic Whitham Equations for the KdV Hierarchy

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/127679We study the Whitham equations for all the higher order KdV equations. The Whitham equations are neither strictly hyperbolic nor genuinely nonlinear. We are interested in the solution of the Whitham equations when the initial values are given by a step function.31 pages, 1 figureExactly Solvable and Integrable SystemsAnalysis of PDEsSelf-Similar Solutions of the Non-Strictly Hyperbolic Whitham Equations for the KdV Hierarchytext
