On Conformal Flexibility of Completeness and Minimizing Geodesics on Hilbert Manifolds

Levin Maier

This article is part of a broader programme investigating which features of finite-dimensional Riemannian geometry persist in infinite dimensions. The Hopf--Rinow theorem fails eve…

On Periodic Geodesics of Half-Lie Groups

Martin Bauer, Levin Maier

A central program in infinite-dimensional Riemannian geometry is to understand which classical finite-dimensional principles remain valid beyond finite dimensions. In this article,…

Topics in Magnetic Geometry: Interpolation, Intersections and Integrability

Lina Deschamps, Levin Maier, Tom Stalljohann

This paper develops new links between contact geometry, magnetic dynamics, and symmetry in exact magnetic systems. First, we establish an interpolation property for Killing magneti…

Magnetic billiards and the Hofer-Zehnder capacity of disk tangent bundles of lens spaces

Johanna Bimmermann, Levin Maier

We compute the Hofer-Zehnder capacity of disk tangent bundles of certain lens spaces with respect to the round metric. Interestingly we find that the Hofer-Zehnder capacity does no…
