Abstract:
Consider the Cauchy problem for a conservation law and assume that an integral functional on its solution is defined. In this note we obtain an Euler-Lagrange equation for the stationary points of this functional. An application to the optimal management of traffic flows is considered.Received: 29 April 2002, Accepted: 24 October 2002, Published online: 4 September 2003Mathematics Subject Classification (2000): 35L65, 49K20, 90B20The authors thank Stefano Bianchini for useful discussions.
