The whitham equations revisited - Taylor & Francis

WebThe Whitham equations are a system of hydrodynamic type equations [12] and in the Riemann invariant coordinates take the form ui t= v i(u)ui x , i= 1,...,N, u = (u 1,...,u N). The original evolution system is usually Lagrangian or Hamiltonian and this prop- erty is usually inherited by the equations of slow modulations.
