Reeb flows without simple global surfaces of section

Juno Kim, Yonghwan Kim and Otto van Koert

Vol. 15 (2022), No. 5, 813–842

We construct, for any given positive integer n, Reeb flows on contact integral homology 3-spheres which do not admit global surfaces of section with fewer than n boundary components. We use a connected sum operation for open books to construct such systems. Moreover, we prove that this property is stable with respect to C4+𝜖-small perturbations of the Hamiltonian given on the symplectization.
