WebJan 1, 2003 · A contact element on a manifold is a hyperplane in the tangent space to the manifold at a point. For a surface F we denote by ST ∗ F the space of all cooriented (transversally oriented) contact elements of F. This space is the spherical cotangent bundle of F. Its natural contact structure is the distribution of tangent hyperplanes given by ...
