On the Rigidity of Hamiltonians which are Zoll Near a Minimum, with an Application to Magnetic Systems and Almost-Kähler Manifolds
Gabriele Benedetti, Johanna Bimmermann, Samanyu Sanjay
We study Hamiltonian systems near a compact symplectic Morse-Bott minimum. Our first result shows that if the flow is Zoll (that is, it induces a free circle action) along a sequen…

Maximal Weinstein neighborhoods of symmetric R-spaces and their symplectic capacities
Johanna Bimmermann
Symmetric R-spaces can be characterized as real forms of Hermitian symmetric spaces, and as such, they are all embedded as Lagrangian submanifolds. We show that their maximal Weins…
