WebNov 11, 2016 · For a vector v ∈ T a M, consider the unique geodesic given by x ( 0) = a, x ˙ ( 0) = v . Put φ t ( v) = x ˙ ( t) . This is a vector in T x ( t) M. The computation in the previous section shows that φ is a flow map of a vector field. Indeed, we have a formula x ¨ = F ( x, x ˙), and this can be represented as a system of differential ... 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.
