Diffeomorphism type via aperiodicity in Reeb dynamics
Myeonggi Kwon, Kevin Wiegand, Kai Zehmisch
We characterise boundary shaped disc like neighbourhoods of certain isotropic submanifolds in terms of aperiodicity of Reeb flows. We prove uniqueness of homotopy and diffeomorphis…

Periodic orbits in virtually contact structures
Youngjin Bae, Kevin Wiegand, Kai Zehmisch
We prove that certain non-exact magnetic Hamiltonian systems on products of closed hyperbolic surfaces and with a potential function of large oscillation admit non-constant contrac…

Two constructions of virtually contact structures
Kevin Wiegand, Kai Zehmisch
Motivated by recent developments in proving the Weinstein conjecture we introduce the notion of covering contact connected sum for virtually contact manifolds and construct virtual…
