Abstract

Consider a closed monotone symplectic manifold (M,ω)(M,\omega). \cite{Gan2} constructed a cyclic open-closed map, which goes from the cyclic homology of the Fukaya category of MM to the S1S^1-equivariant quantum cohomology of MM. In this paper, we show that with mod pp coefficients, Ganatra's cyclic open-closed map is compatible with a certain Z/p\mathbb{Z}/p-equivariant open-closed map under the natural Z/p\mathbb{Z}/p-Gysin type comparison map for Hochschild homology. Along with the proof, this paper gives a new homotopy theoretic framework for studying open-closed maps in symplectic topology. These will be used in an upcoming work \cite{Che} to study mod pp equivariant enumerative invariants such as the Quantum Steenrod operations. The main insights of this paper are: 1) a Z/p\mathbb{Z}/p-Gysin comparison result for (A\mathcal{A}_{\infty}-) cyclic objects, 2) a new construction of the open-closed map using operadic Floer theory of \cite{AGV}, which gives rise to a new interpretation of its `S1S^1-equivariant' property, and 3) comparison of the new construction with its classical counterpart.
