Some applications of canonical metrics to Landau–Ginzburg models

It is known that a given smooth del Pezzo surface or Fano threefold X admits a choice of log Calabi-Yau compactified mirror toric Landau-Ginzburg model (with respect to certain fixed Kahler classes and Gorenstein toric degenerations). Here we consider the problem of constructing a corresponding map Theta from a domain in the complexified Kahler cone of X to a well-defined, separated moduli space M of polarised manifolds endowed with a canonical metric. We prove a complete result for del Pezzos and a partial result for some special Fano threefolds. The construction uses some fundamental results in the theory of constant scalar curvature K\"ahler metrics. As a consequence M parametrises K-stable manifolds and the domain of Theta is endowed with the pullback of a Weil-Petersson form.
