Pairs of positive radial solutions for a Minkowski-curvature Neumann problem with indefinite weight
Alberto Boscaggin, Guglielmo Feltrin
We prove the existence of a pair of positive radial solutions for the Neumann boundary value problem \begin{equation*} \begin{cases} \, \mathrm{div}\,\Biggl{(} \dfrac{\nabla u}{\sq…
Multiplicity of solutions for the Minkowski-curvature equation via shooting method
Alberto Boscaggin, Francesca Colasuonno, Benedetta Noris
In this paper we prove the existence and the multiplicity of radial positive oscillatory solutions for a nonlinear problem governed by the mean curvature operator in the Lorentz-Mi…
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…
High multiplicity and chaos for an indefinite problem arising from genetic models
Alberto Boscaggin, Guglielmo Feltrin, Elisa Sovrano
We deal with the periodic boundary value problem associated with the parameter-dependent second-order nonlinear differential equation \begin{equation*} u'' + cu' + \bigr{(} λa^{+}(…
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,…
Periodic solutions to a forced Kepler problem in the plane
A. Boscaggin, W. Dambrosio, D. Papini
Given a smooth function , -periodic in the first variable and satisfying for some as , we…
