The space of linear anti-symplectic involutions is a homogenous space
Peter Albers, Urs Frauenfelder
In this note we prove that the space of linear anti-symplectic involutions is the homogenous space $Gl(n,\R)\Sp(n)$. This result is motivated by the study of symmetric periodic orb…

The Conley-Zehnder indices of the rotating Kepler problem
Peter Albers, Joel W. Fish, Urs Frauenfelder +1
We determine the Conley-Zehnder indices of all periodic orbits of the rotating Kepler problem for energies below the critical Jacobi energy. Consequently, we show the universal cov…
