title: The Aronsson-Euler Equation for 1-dimensional Hamiltonians
abstract: In relation with the Hamilton-Jacobi equation $H(x, D_x u) =c$,
Craig Evans introduced the Aronsson-Euler equation
$$
-D_x^2 ( {\partial H\over\partial p}(xD_x u), {\partial H\over\partial p}(xD_x u) )
- \langle {\partial H\over\partial x}(xD_x u), {\partial H\over\partial x}(xD_x u) \rangle
=0 \ .
$$
He showed relations with weak KAM theory. Yifeng Yu has extended the
work of Evans. In this joint work with Antonio Siconolfi, we study the
1-dimensional case. We show by examples that the Aubry set cannot be
the uniqueness set for this Aronsson-Euler equation. We describe a
uniqueness set.
