Auroux's mirror correspondence conjecture for restriction, wrapping, and lifting functors

Let XX, DD, and ZZ be the algebraic-geometric mirror objects, with inclusion iX:XZi_X:X\to Z, projection πX:ZX\pi_X:Z\to X, and inclusion and projection

jD:KXDZ,pD:KXDD.j_D:K_X|_D\to Z,\qquad p_D:K_X|_D\to D.

Let q:Coh(Z)Sing(Z)q:\operatorname{Coh}(Z)\to\operatorname{Sing}(Z) be the quotient functor, and let Sing(Z)Coh(D)\operatorname{Sing}(Z)\to\operatorname{Coh}(D) be the Knörrer periodicity equivalence. The Fukaya-side functors are the restriction functor ρ\rho, the wrapping-around-HH functor α0\alpha_0, the wrapping-at-infinity functor α\alpha_\infty, and the lifting functor jj.

Auroux's mirror correspondence conjecture. Under homological mirror symmetry, ρ\rho corresponds to the composite of qq with the Knörrer periodicity equivalence; α0\alpha_0 corresponds to iXi_{X*}; α\alpha_\infty corresponds to πX\pi_X^*; and jj corresponds to

jDpD(KXD).j_{D*}p_D^*(K_X|_D\otimes\mathord\cdot\,).

These conjectures identify natural Fukaya-category functors with quotient, pushforward, pullback, and tensor-pushforward functors in algebraic geometry. The source attributes the correspondence to Auroux and discusses the individual claims in the indicated sections; the supplied text gives no evidence that they have been resolved.
