WebJul 14, 2024 · Indeed the parallel transport of a horizontal vector field along a horizontal geodesic may not be horizontal. This will be detailed in the next subsection and constitutes a good example of metric for which computing geodesics is easier than computing parallel transport, although the former is a variational problem and the latter is a linear ODE. WebFig.1: Step of the parallel transport of the vector w (blue arrow) along the geodesic (solid black curve). J w is computed by central nite di erence with the perturbed geodesics " and , integrated with a second-order Runge-Kutta scheme (dotted black arrows). A fan of geodesics is formed.

WebAug 1, 2024 · Parallel transport along geodesics on a sphere differential-geometry 1,068 You're correct in both cases. The latitude θ = π / 2 is a geodesic and since the coordinate frame ∂ / ∂θ, ∂ / ∂ϕ is parallel along that curve, the coefficients of V will be constant. In the second case, the spherical coordinate system fails at θ = 0 and θ = π. WebParallel transport of a vector around a closed loop (from A to N to B and back to A) on the sphere. The angle by which it twists, , is proportional to the area inside the loop. In … tartan home page
