Contact triad connection of contact manifolds in almost contact moving frame

Yong-Geun Oh

The notion of \emph{contact triad connection} on contact triads $(Q, λ, J_{ξ})$ was introduced by Wang and the present author in early 2010's from scratch as the contact analog to the…

Strict contactomorphisms are scarce

Yong-Geun Oh, Yasha Savelyev

The notion of non-projectible contact forms on a given compact manifold $M$ is introduced by the first-named author in [Ohb], the set of which he also shows is a residual subset of…

Leafwise de Rham cohomology of generic Reeb foliations

Yong-Geun Oh

In this paper, we prove that there exists a residual subset of contact forms $λ$ (if any) on any compact connected orientable manifold $M$ for which the foliation de Rham cohomolog…
