Existence of a positive hyperbolic Reeb orbit in three spheres with finite free group actions
Abstract
Let be a non-degenerate contact three manifold. D. Cristfaro-Gardiner, M. Hutshings and D. Pomerleano showed that if is torsion, then the Reeb vector field of has infinity many Reeb orbits otherwise is a lens space or three sphere with exaxtly two simple elliptic orbits. In the same paper, they also showed that if , has a simple positive hyperbolic orbit directly from the isomorhphism between Seiberg-Witten Floer homology and Embedded contact homology. In addition to this, they asked whether with infinity many simple orbits also has a positive hyperbolic orbit under . In the present paper, we answer this question under with nontrivial finite free group actions, especially lens spaces with odd as quotient spaces of .
