Planar Hamiltonian systems: index theory and applications to the existence of subharmonics
Alberto Boscaggin, Eduardo Muñoz-Hernández
We consider a planar Hamiltonian system of the type , where is a function periodic in the time variable, s…
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…
Uniqueness of positive solutions for boundary value problems associated with indefinite -Laplacian type equations
Alberto Boscaggin, Guglielmo Feltrin, Fabio Zanolin
The paper provides a uniqueness result for positive solutions of the Neumann and periodic boundary value problems associated with the -Laplacian equation \begin{equation*} \bigl…
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…
Positive solutions for a Minkowski-curvature equation with indefinite weight and super-exponential nonlinearity
Alberto Boscaggin, Guglielmo Feltrin, Fabio Zanolin
We investigate the existence of positive solutions for a class of Minkowski-curvature equations with indefinite weight and nonlinear term having superlinear growth at zero and supe…
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…
