The method of proof is an elegant application of the Leray-Serre spectral sequence to the path-loop fibration. This result is one of the first spectacular applications of homotopy theory in differential geometry. In [Gr], M. Gromov improved the classical theorem of Morse above in the direction of a quantitative statement: let N(p,q;2) denote the number of geodesics in M joining p and q of length less than 2. If M is a compact, connected Riemannian manifold with finite fundamental group, and p and q are non-conjugate points in M, then there is a positive constant C, depending on M, such that
