Torus-equivariant homological mirror symmetry for toric Fano stacks
Torus-equivariant homological mirror symmetry for toric Fano stacks
Let be a convex lattice polytope in containing the origin in its interior. Let be the associated toric Fano stack, let be the -dimensional torus acting on , and let be the pullback of a Laurent polynomial mirror to the universal cover of . Write for the derived category of -equivariant coherent sheaves. Torus-equivariant homological mirror symmetry conjecture. There is an equivalence of triangulated categories
This equivariant refinement implies ordinary homological mirror symmetry for and for finite torus quotient stacks. The paper proves it when is projective space, but the assertion for general convex lattice polytopes remains open in the source.
