Burago, D. Yu. A new approach to the computation of the entropy of a geodesic flow and similar dynamical systems. (English. Russian original) Zbl 0706.58050 Sov. Math., Dokl. 37, No. 2, 501-504 (1988); translation from Dokl. Akad. Nauk SSSR 299, No. 5, 1041-1044 (1988). The author studies the geodesic flow on a closed Riemannian manifold aiming at expressions for the entropy for a focusing property of geodesics. He also gets a new example of a flow with positive entropy.
