Global homoclinic bifurcation for damped systems.
Multiple closed orbits for singular conservative systems via geodesic theory
Homoclinic and period-doubling bifurcations for damped systems
Aubry sets and the differentiability of the minimal average action in codimension one
Let (,, ) be a Lagrangian periodic of period in ,..., ,. We shall study the non self intersecting functions : minimizing ; non self intersecting means that, if ( + ) + = ( ) for some and ( , ) × , then = ( + ) + . Moser has shown that...
