Multiple periodic solutions of Hamiltonian systems in the plane
KeywordsMultiplicity of periodic solutions, nonlinear boundary value problems, Poincaré-Birkhoff Theorem
AbstractOur aim is to prove a multiplicity result for periodic solutions of Hamiltonian systems in the plane, by the use of the Poincaré-Birkhoff Fixed Point Theorem. Our main theorem generalizes previous results obtained for scalar second order equations by Lazer and McKenna [< i> Large scale oscillatory behaviour in loaded asymmetric systems< /i> , Ann. Inst. H. Poincaré Anal. Non Linéaire < b> 4< /b> (1987), 243–274] and Del Pino, Manasevich and Murua [< i> On the number of $2\pi$-periodic solutions for $u''+g(u) =s(1+h(t))$ using the Poincaré–Birkhoff Theorem< /i> , J. Differential Equations < b> 95< /b> (1992), 240–258].
