Simple variational splines on manifolds
Riemannian splines have been studied since the 1990's and in fact one of the leading groups is Fatima Leite's at Coimbra. A simple spline is a curve controlled by a force, whose normal component deviates it from the geodesic path, whereas the tangential component controls the speed. We revisit the theme with ideas from Geometric Mechanics.
