Toric homological mirror symmetry monodromy conjecture

Let Xˇ\check X be a toric variety with dd rays in its fan, and let TT be an algebraic torus of rank dim(Xˇ)\dim(\check X). Let V(EA)V(E_A) be the hypersurface cut out by the principal AA-determinant of a matrix AA determined by the toric GIT problem. Toric HMS monodromy conjecture. There is an action

π1(AdV(EA)T)Auteq(Db(Xˇ)).\pi_1\left(\frac{\mathbb A^d\setminus V(E_A)}{T}\right)\longrightarrow \operatorname{Auteq}\left(D^b(\check X)\right).

This proposes the categorical monodromy action associated with the toric mirror-moduli space, but the source does not state a resolution of the conjecture.
