Equivariant identification of iterated local symplectic homology with Z_k-invariant local Floer homology
Prove that for any isolated closed Reeb orbit x and any integer k≥1, the equivariant local symplectic homology CH(x^k;Q) is isomorphic to the Z_k-invariant part of the local Floer homology HF(ϕ^k;Q) of the Poincaré return map ϕ of x, and that the non-equivariant local symplectic homology SH(x^k;Q) decomposes as HF(ϕ^k;Q)^{Z_k} ⊕ HF(ϕ^k;Q)^{Z_k}[−1].

Conjecturally, CH(xk;Q) = HF(ϕk;Q){Z_k} and SH(xk;Q) = HF(ϕk;Q){Z_k} ⊕ HF(ϕk;Q){Z_k}[−1] for all k ∈ N; see [GH M].
