WebbSimple closed curves can most easily be studied via their geodesic repre sentatives, and so we begin with the fact that every surface may be endowed with a constant-curvature Riemannian metric, and we study the relation be tween curves, the fundamental group, and geodesics. We then introduce the geometric intersection number, which we think ...
