Abstract
We consider the projection to configuration space of invariant tori in a timereversible Hamiltonian system at a point of zero momentum. At such pointsthe projection has rank zero and the resulting caustic has a corner. We usecaustic equivalence of Lagrangian mappings to find a normal form for such acorner in 3 degrees of freedom.
