Add to ORKGI try to give a general description of the dynamics of the solutions for a planar hamiltonian system with positively homogeneous hamiltonian function and periodic forcing term. Most of the results obtained are already known in the special case of a scalar second-order differential equation with asymmetric nonlinearity
