Webnegative then the geodesic flow is an Anosov flow [2] and w1(M) has ex-ponential growth [9]. It is because entropy describes the way geodesics spread out that sectional curvature seems the most relevant type of curva-ture. COROLLARY [8]. The compact fundamental domain N determines a set of generators IF= f{a e w1(M); aNf NN 0}. Let w(k) be the ... Geodesics can be understood to be the Hamiltonian flows of a special Hamiltonian vector field defined on the cotangent space of the manifold. The Hamiltonian is constructed from the metric on the manifold, and is thus a quadratic form consisting entirely of the kinetic term. The geodesic equations are second-order differential equations; they can be re-expressed as first-order equations by introducing additional independent variables, as shown below. Note that a co…
