WebMar 6, 2024 · Parallel 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, α, is proportional to the area inside the loop. In geometry, parallel transport (or parallel translation [lower-alpha 1]) is a way of transporting geometrical data along smooth curves in a manifold. 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.
