Example 5.4.

If 𝒳{\mathcal{X}} is toroidal, then 𝒳{\mathcal{X}} is lc, and 𝒳{\mathcal{X}} is dlt if and only if it is snc. Following [dFKX12, KNX15], we could say that an lc model 𝒳{\mathcal{X}} is qdlt (for quotient of dlt) if its lc centers are contained in a toroidal open subset 𝒰⊂𝒳{\mathcal{U}}\subset{\mathcal{X}}.
