By using open book techniques we give an alternative proof of a theorem about the existence of contact structures on five-manifolds due to Geiges. The theorem asserts that simply-connected five-manifolds admit a contact structure in every homotopy class of almost contact structures.
We construct a version of rational Symplectic Field Theory for pairs , where is an exact symplectic manifold, where is an exact Lagrangian submanifold with components subdivided into subsets, and where both and have cylindrical ends. The theory associates to a -graded chain complex of vector spaces over , filtered with filtration levels. The corresponding -level spectral sequence is invariant under deformations of and has the following property: if is obtained by joining a...
In this paper we firstly define a tangential Lichnerowicz cohomology on foliated manifolds. Next, we define tangential locally conformal symplectic forms on a foliated manifold and we formulate and prove some results concerning their stability.
We perform symplectic embeddings of ‘thin’ discs into a small ball in arbitrary dimension, using the symplectic folding construction.
