Periodic solutions to relativistic Kepler problems: a variational approach
Alberto Boscaggin, Walter Dambrosio, Duccio Papini
We study relativistic Kepler problems in the plane. At first, using non-smooth critical point theory, we show that under a general time-periodic external force of gradient type the…
Unbounded solutions to systems of differential equations at resonance
Alberto Boscaggin, Walter Dambrosio, Duccio Papini
We deal with a weakly coupled system of ODEs of the type with locally Lipschitz continuous and…
On the minimality of Keplerian arcs with fixed negative energy
Vivina Barutello, Alberto Boscaggin, Walter Dambrosio
We revisit a classical result by Jacobi on the local minimality, as critical points of the corresponding energy functional, of fixed-energy solutions of the Kepler equation joining…
Parabolic orbits in Celestial Mechanics: a functional-analytic approach
Alberto Boscaggin, Walter Dambrosio, Guglielmo Feltrin +1
We prove the existence of half-entire parabolic solutions, asymptotic to a prescribed central configuration, for the equation \begin{equation*} \ddot{x} = \nabla U(x) + \nabla W(t,…
