...Since then, a number of papers have been devoted to the generalization of this variational theory in many other contexts: interpolation problems [5], collision avoidance of multiple agents [2] and quantum splines interpolation [1], among others....

...Inspired by the goal of gaining a better understanding of trajectories which minimize a weighted combination of the covariant acceleration and the velocity of the system in the presence of a repulsive potential which is used to avoid a static circular obstacle, in [5] we extended the problem to the trajectories that also interpolate some points on the...

...tems and Fiorelli and Leonard [36] for multi-agent formation. The mathematical foundations for the existence of such a smooth functions on any smooth manifold can be found in the works of Smale [42], [25]. In this paper, we aim to generate trajectories interpolating prescribed points and avoiding multiple obstacles in the workspace via the study of a second order variational problem on a Riemannian ma...

...n M, is a map that assigns to any two smooth vector fields X and Y on M a new vector field, r XY, called the covariant derivative of Y with respect to X. For the properties of r, we refer the reader to [11], [12], [39]. Consider a vector field W along a curve x on M. The sth-order covariant derivative along x of W is denoted by DsW dt s , s 1. We also denote by Ds+1x dt +1 the sth-order covariant deriva...
