SMOOTH OPTIMAL SYNTHESIS FOR INFINITE HORIZON
VARIATIONAL PROBLEMS
Andrei A. Agrachev1
and Francesca C. Chittaro2
Abstract. We study Hamiltonian systems which generate extremal flows of regular variational prob-
lems on smooth manifolds and demonstrate that negativity of the generalized curvature of such a
system implies the existence of a global smooth optimal synthesis for the infinite horizon problem.
We also show that in the Euclidean case negativity of the generalized curvature is a consequence of
the convexity of the Lagrangian with respect to the pair of arguments. Finally, we give a generic
classification for 1-dimensional problems.
