Contact open books with flexible pages

  title={Contact open books with flexible pages},
  author={Jonathan Bowden and D. Crowley},
We give an elementary topological obstruction for a (2q+1)-manifold M to admit a contact open book with flexible Weinstein pages: if the torsion subgroup of the q-th integral homology group is non-zero, then no such contact open book exists. We achieve this by proving that a symplectomorphism of a flexible Weinstein manifold acts trivially on cohomology. We also produce examples of non-trivial loops of flexible contact structures using related ideas. 


We show the existence of a contractible periodic Reeb orbit for any contact structure supported by an open book whose binding can be realized as a hypersurface of restricted contact type in aExpand
Contact Manifolds with Flexible Fillings
We prove that all flexible Weinstein fillings of a given contact manifold with vanishing first Chern class have isomorphic integral cohomology. As an application, we show that in dimension at least 5Expand
Lecture notes on stabilization of contact open books
This note explains how to relate some contact geometric operations, such as surgery, to operations on an underlying contact open book. In particular, we shall give a simple proof of the fact thatExpand
The topology of Stein fillable manifolds in high dimensions II
We give a bordism-theoretic characterisation of those closed almost contact (2q+1)-manifolds (with q > 2) which admit a Stein fillable contact structure. Our method is to apply Eliashberg'sExpand
In this paper I give a completed topological characterization of Stein manifolds of complex dimension >2. Another paper (see [E14]) is devoted to new topogical obstructions for the existence of aExpand
Kernel of the variation operator and periodicity of open books
Abstract We consider a parallelizable 2 n -manifold F which has the homotopy type of the wedge product of n -spheres and show that the group of pseudo-isotopy classes of orientation preservingExpand
Existence and classification of overtwisted contact structures in all dimensions
We establish a parametric extension h-principle for overtwisted contact structures on manifolds of all dimensions, which is the direct generalization of the 3-dimensional result from [12]. ItExpand

Symplectic homology and the Eilenberg-Steenrod axioms
We give a definition of symplectic homology for pairs of filled Liouville cobordisms, and show that it satisfies analogues of the Eilenberg-Steenrod axioms except for the dimension axiom. TheExpand
