Equivariant symplectic homology and multiple closed Reeb orbits (1305.1245v2)
Published 6 May 2013 in math.SG and math.DS
Abstract: We study the existence of multiple closed Reeb orbits on some contact manifolds by means of $S1$-equivariant symplectic homology and the index iteration formula. It is proved that a certain class of contact manifolds which admit displaceable exact contact embeddings, a certain class of prequantization bundles, and Brieskorn spheres have multiple closed Reeb orbits.
