Bifurcation of closed orbits of Hamiltonian systems with application to geodesics of the Schwarzschild metric

Alberto Boscaggin, Walter Dambrosio, Guglielmo Feltrin

We investigate bifurcation of closed orbits with a fixed energy level for a class of nearly integrable Hamiltonian systems with two degrees of freedom. More precisely, we make a jo…

Multiplicity and symmetry breaking for supercritical elliptic problems in exterior domains

Alberto Boscaggin, Francesca Colasuonno, Benedetta Noris +1

We deal with the following semilinear equation in exterior domains \[-Δu + u = a(x)|u|^{p-2}u,\qquad u\in H^1_0({A_R}), \] where $A_{R} := {x \in R^{N} : ∣ x ∣ > R}$ , $N\ge 3…
