Contact surgery and symplectic caps
arXiv:1811.00387 · doi:10.1112/blms.12332
Abstract
In this note we show that a closed oriented contact manifold is obtained from the standard contact sphere of the same dimension by contact surgeries on isotropic and coisotropic spheres. In addition, we observe that all closed oriented contact manifolds admit symplectic caps.
