Abstract:

Given any equivariant coherent sheaf $\mathcal {L}$ on a compact semi-positive toric orbifold $\mathcal {X}$, its SYZ T-dual mirror dual is a Lagrangian brane in the Landau-Ginzburg mirror. We prove that the oscillatory integral of the equivariant superpotential in the Landau Ginzburg mirror over this Lagrangian brane is the genus-zero $1$-descendant Gromov-Witten potential with a Gamma-type class of $\mathcal {L}$ inserted.
