Rotation numbers for curves on a torus

We define a regular homotopy invariant of closed curves on a surface, and give a formula for the rotation number of closed curves on toms, which is analogous to the Whitney formula for planar curves. As an application, we show a necessary condition for a Gauss word to be realized on toms.
