Proposition 3.8.

Let AA be an abelian KK-variety of dimension nn. Then the essential skeleton Sk⁡(A)\mathrm{Sk}(A) of AA coincides with Berkovich’s canonical skeleton Δ⁡(A)\Delta(A). If AA has semi-abelian reduction and 𝒫\mathscr{P} is a Künnemann-Mumford model of AA over RR, then 𝒫\mathscr{P} is a good minimal dlt-model that satisfies assumption (2). If AA has purely toric reduction, then the non-archimedean SYZ fibration ρ𝒫\rho_{\mathscr{P}} coincides with Berkovich’s canonical retraction ρA\rho_{A}. In particular, ρ𝒫\rho_{\mathscr{P}} is an nn-dimensional affinoid torus fibration.
