Lekili–Evans comparison conjecture for Hamiltonian action maps
Lekili–Evans comparison conjecture for Hamiltonian action maps
Let act Hamiltonianly on a monotone symplectic manifold . The action gives an -algebra map
Lekili and Evans' construction gives a map from the endomorphisms of the cotangent fiber in the wrapped Fukaya category of to the endomorphisms of the diagonal in the Fukaya category of ; after identifying the relevant codomains, Lekili–Evans comparison conjecture. As -algebra maps, the map constructed from the Hamiltonian action is homotopic to the map constructed by Lekili and Evans. Part of the conjecture is that this equivalence is intertwined by a natural chain-level, -algebra equivalence between Hochschild cochains and endomorphisms of the diagonal. The conjecture compares a map built from bundles and localization with one built from Lagrangian correspondences and quilts. The required chain-level identification of codomains is part of the assertion, and no resolution is stated.
