      A geodesic segment in X is an isometry c : I + X, where I is a closed interval in Iw. A geodesic in X is a map c : It8 + X such that for each closed interval I c R, the map c 11 : I -+ X is a geodesic segment. A local geodesic segment (usually called geodesic arc) in X is a map c : I + X such

      Along any geodesic γ, the set of Jacobi fields is a 2n-dimensional linear subspace of T(γ). Proof. Let p = γ(a) be any point on γ, and consider the map from the set of Jacobi fields along γ to T pM⊕T pM by sending J to (J(a),D tJ(a)). The preceding proposition says precisely that this map is bijective.

In information geometry, the distance be-tween two points on a manifold is analogous to the difference in information between them, and is defined by the Fisher in-formation metric. This measures the amount of information a
