Theorem 4.97.

Let Σ\Sigma be a complete fan in NℝN_{\mathbb{R}}. Let Ψ\Psi be a support function on Σ\Sigma. Then the correspondence of Theorem 4.81 induces a bijective correspondence between the set of rational piecewise affine concave functions ψ\psi with rec⁡(ψ)=Ψ\operatorname{rec}(\psi)=\Psi and the set of equivalence classes of semipositive toric models of (XΣ,DΨ)(X_{\Sigma},D_{\Psi}) over SS.
