Bott-integrability of overtwisted contact structures
Hansjörg Geiges, Jakob Hedicke, Murat Sağlam
We show that an overtwisted contact structure on a closed, oriented 3-manifold can be defined by a contact form having a Bott-integrable Reeb flow if and only if the Poincaré dual…

Bott-integrable Reeb flows on 3-manifolds
Hansjörg Geiges, Jakob Hedicke, Murat Sağlam
This paper is devoted to studying a notion of Bott integrability for Reeb flows on contact 3-manifolds. We show, in analogy with work of Fomenko-Zieschang on Hamiltonian flows in d…

Why bootstrapping for -holomorphic curves fails in
Hansjörg Geiges, Murat Sağlam, Kai Zehmisch
We present a simple example for the failure of the Calderón-Zygmund estimate for the -operator when the Sobolev -norms are replaced by the -norms. This…
