Definition 1.18. Fix a lattice N. Let (Σ, W ) be a pair consisting of a fan Σ in NR and a complex vector subspace W ⊂ NC. A cone τ ∈ Σ is called non-dicritical if relint(τ ) ∩ W ∩ N 6= ∅ if and only if τ ⊂ W. We say (Σ, W ) satisfies the condition (†) if τ is non-dicritical for all τ ∈ Σ. (pdf) (Chang 和 Chen, 2023, p. 8)
