Subharmonic solutions of a nonconvex noncoercive hamiltonian system
RAIRO - Operations Research - Recherche Opérationnelle, Tome 38 (2004) no. 1, pp. 27-37.

In this paper we study the existence of subharmonic solutions of the hamiltonian system

Jx ˙+u * ∇G(t,u(x))=e(t)
where u is a linear map, G is a C 1 -function and e is a continuous function.
