Hironaka.Resolution.Analytic.Functor.FamilyClosedEmbedding

The per-open closed-embeddings predicate for family functors #

The commutation with closed embeddings of [Kol07, 34.3], in the form of [Kol07, Theorem 103, (3)], per relatively compact open: the family functor B at the model (E, ψ₀) commutes with closed embeddings whenever E = ∅, through the family functor B' at the model 𝕜^{n−s}; this is the per-open version of AnalyticBlowUpSequenceAssignment.CommutesWithClosedEmbeddingsOfEmptyDivisor (Hironaka.Manifold.FiniteSuccession.Functor.Basic), the (n−s)-dimensional family read at U ∩ S and pushed forward by BlowUpSequence.pushforwardRestrict.

B commutes with closed embeddings whenever E = ∅, through B' — for every closed submanifold τ : S ↪ M of codimension s, ideal sheaves 𝓘 on M and J on the bundled S with 𝓘 ⊇ I_S and J = τ^* 𝓘, and every relatively compact open U ⊆ M, the value of B on U is the push-forward of the value of B' on U_S.
