WebA K-contact manifold is a smooth manifold M with a contact form α whose Reeb ﬂow preserves a Riemannian metric g on M. If M is closed and connected, then the closure of the Reeb ﬂow in the isometry group of (M,g) is a torus. The dimension of the torus is called the rank of the K-contact manifold (M,α).

WebA contact structure on an odd dimensional manifold is a smoothly varying family of codimension one subspaces of each tangent space of the manifold, satisfying a non-integrability condition. The family may be described as a section of a bundle as follows: WebIn this talk, I will show that exact fillings (with vanishing first Chern class) of a flexibly fillable contact (2n-1)-manifold share the same product structure on cohomology if one of the multipliers is of even degree smaller than n-1. The main argument uses Gysin sequences from symplectic cohomology twisted by sphere bundles.
