Proposition 7.5.

If φ∈PSH⁡(X,θ)\varphi\in\PSH(X,\theta) and 𝒳\mathcal{X} is an SNC model on which θ\theta is determined, then:

  • (i)

    φ∘emb𝒳\varphi\circ\emb_{\mathcal{X}} is continuous on Δ𝒳\Delta_{\mathcal{X}} and convex on each face;

  • (ii)

    φ∘p𝒳\varphi\circ p_{\mathcal{X}} is continuous on XX and φ≤φ∘p𝒳\varphi\leq\varphi\circ p_{\mathcal{X}}.
