Symplectic compactification conjecture for polarized toric degenerations

Let XD\mathcal{X}\rightarrow D be a polarized toric degeneration with intersection complex (Bˇ,Pˇ)(\check B,\check{\mathcal P}). Let ωt\omega_t be a Kähler form on Xt\mathcal{X}_t representing the first Chern class of the polarization. Let Γ\Gamma denote the discriminant locus of Bˇ\check B. Symplectic compactification conjecture. There is an open set UˇBˇ\check U\subseteq\check B such that BˇUˇ\check B\setminus\check U retracts onto Γ\Gamma, and Xt\mathcal{X}_t is a symplectic compactification of Xˇ(Uˇ)\check X(\check U) for any tt. This predicts a symplectic realization of the intersection complex away from its discriminant locus and is part of the proposed geometric description of toric degenerations.
