Symplectic geometry and space mission design
Cengiz Aydin, Urs Frauenfelder, Otto van Koert +2
Using methods from symplectic geometry, the second and fifth authors have provided theoretical groundwork and tools aimed at analyzing periodic orbits, their stability and their bi…

RSFT functors for strong cobordisms and applications
Agustin Moreno, Zhengyi Zhou
We extend the hierarchy functors of [33] to the case of strong symplectic cobordisms, via deformations with Maurer--Cartan elements. In particular, we prove that the concave bounda…

On doubly symmetric orbits
Urs Frauenfelder, Agustin Moreno
In this article, for Hamiltonian systems with two degrees of freedom, we study doubly symmetric periodic orbits, i.e. those which are symmetric with respect to two (distinct) commu…
