Abstract (EN)
The existence is proved, by means of variational arguments, of infinitely many heteroclinic solutions connecting possibly degenerate equilibria for a class of almost periodic Lagrangian system. An analogous multiplicity result is then established for homoclinic solutions of systems with an almost periodic singular potential.
Subjects / Keywords
Lagrangian systems; heteroclinic and homoclinic orbits; almost periodicity; variational arguments
