Ricci-flat convergence conjecture for minimal models with Kodaira dimension zero

About 17 years old · traced to

Let XX be a minimal model with kod(X)=0\textnormal{kod}(X)=0 and numerically trivial KXK_X, and let [H][H] be the initial Kähler class. Consider the unnormalized Kähler-Ricci flow

∂ω∂t=−Ric⁡(ω).\frac{\partial \omega}{\partial t}=-\operatorname{Ric}(\omega).

Ricci-flat convergence conjecture. As t→∞t\to\infty, the flow converges in the Gromov-Hausdorff sense to the unique Ricci-flat Kähler metric in [H][H]. Smooth convergence is known when XX is smooth, and weak convergence is known for log terminal singularities; the full formulation is therefore motivated by these partial results.
