On the Whitham Hierarchies: Reductions and Hodograph Solutions
Exactly Solvable and Integrable Systems
2009-11-07 v1
Abstract
A general scheme for analyzing reductions of Whitham hierarchies is presented. It is based on a method for determining the -function by means of a system of first order partial differential equations. Compatibility systems of differential equations characterizing both reductions and hodograph solutions of Whitham hierarchies are obtained. The method is illustrated by exhibiting solutions of integrable models such as the dispersionless Toda equation (heavenly equation) and the generalized Benney system.
