Long-Time Asymptotics for the Korteweg-de Vries Equation via Nonlinear Steepest Descent

Katrin Grunert and Gerald Teschl

Abstract
We apply the method of nonlinear steepest descent to compute the long-time asymptotics of the Korteweg-de Vries equation for decaying initial data in the soliton and similarity region. This paper can be viewed as an expository introduction to this method.
