%0 Journal Article %T Contact Homology of Orbit Complements and Implied Existence %A Al Momin %J Mathematics %D 2010 %I arXiv %R 10.3934/jmd.2011.5.409 %X For Reeb vector fields on closed 3-manifolds, cylindrical contact homology is used to show that the existence of a set of closed Reeb orbit with certain knotting/linking properties implies the existence of other Reeb orbits with other knotting/linking properties relative to the original set. We work out a few examples on the 3-sphere to illustrate the theory, and describe an application to closed geodesics on $S^2$ (a version of a result due to Angenent). %U http://arxiv.org/abs/1012.1386v2
