Scattering Dynamics and Chaotic Motions in a Relativistic Two-Centre Problem
Stefano Baranzini, Gian Marco Canneori
We study the planar relativistic two-centre problem at fixed energy, including a class of perturbations of the Keplerian potential. Up to a reparametrisation of time, the relativis…
Symmetric solutions of the -body problem: a numerical study of Floquet multipliers and Morse indices
Diego Berti, Gian Marco Canneori, Roberto Ciccarelli +3
In this paper, we consider periodic solutions of the -body problem that satisfy symmetry constraints, expressed through invariance under finite group actions. We focus on their…
Frozen planet orbits for the -electron atom
Stefano Baranzini, Gian Marco Canneori, Susanna Terracini
We seek periodic trajectories of a system of multiple mutually repelling electrons on a half-line, with an attractive nucleus sitting at the origin. We adopt a variational viewpoin…
Equivariant optimisation for the gravitational -body problem: a computational factory of symmetric orbits
Vivina Barutello, Mattia G. Bergomi, Gian Marco Canneori +4
In this paper we present \texttt{SymOrb.jl}, a software which combines group representation theory and variational methods to provide numerical solutions of singular dynamical syst…
