Equivariant wrapped Floer homology and symmetric periodic Reeb orbits

Abstract: The aim of this article is to apply a Floer theory to study symmetric periodic Reeb orbits. We define positive equivariant wrapped Floer homology using a (anti-)symplectic involution on a Liouville domain and investigate its algebraic properties. By a careful analysis of index iterations, we obtain a non-trivial lower bound on the minimal number of geometrically distinct symmetric periodic Reeb orbits on a certain class of real contact manifolds. This includes non-degenerate real dynamically convex star-shaped… Show more

“…Denote the set of contractible, as an element of π 1 ( W , L), Hamiltonian 1-chords by P L (H). We associate the index |x| = −µ(x) − n 2 ∈ Z for each non-degenerate contractible 1-chord in P L (H), where µ(x) is the Maslov index defined in [20,Definition 2.3]. Assume that c 1 (T W ) = 0 and π 1 (L) = 0 for well-definedness of µ(x).…”
