Abstract: A Second Order PDE with n-independent variables
can be geometrically interpreted as a hypersurface
in the manifold of Lagrangian subspaces of a 2n+1-dimensional
contact manifold. After a revision of the geometry of Grassmanian
of Lagrangian planes in a symplectic 2n-dimensional space,
we develop a geometric theory of characteristics of second order PDE's.
