The Seidel-element and Jacobian-generator conjecture for compact toric manifolds

Let XX be a compact toric manifold, not necessarily semi-Fano. Let QH(X,ωq)QH^*(X,\omega_q) denote its small quantum cohomology, let WqLFW_q^{\mathrm{LF}} be the Landau–Ginzburg potential, and let SlS^{\circ}_l be the normalized Seidel elements. The monomials ZlZ_l are the generators associated with the toric divisors in the Jacobian ring Jac(WqLF)\operatorname{Jac}(W_q^{\mathrm{LF}}).

Seidel-element and Jacobian-generator conjecture. The isomorphism

QH(X,ωq)Jac(WqLF)QH^*(X,\omega_q)\overset{\simeq}{\longrightarrow}\operatorname{Jac}(W_q^{\mathrm{LF}})

maps each normalized Seidel element SlS^{\circ}_l to the corresponding generator ZlZ_l.

This extends the theorem established in the semi-Fano case to arbitrary compact toric manifolds. In the non-semi-Fano case, the potential is generally a Laurent series over the Novikov ring rather than a Laurent polynomial, but the monomials ZlZ_l are still defined. The source gives no resolution of the conjecture.
